Refined analysis of spatial distribution of flood hazard vulnerability based on VSD framework——taking Changchun City as an example

LI Ming;ZHAO Hongyu;ZHANG Shiyu;ZHANG Mingyu;

It is an important way to reduce urban risk and enhance climate resilience by identifying the vulnerable areas of urban floods and proposing corresponding strategies through flood hazard vulnerability refinement analysis. Taking Changchun City as an example, the VSD(Vulnerability scoping diagram)assessment framework and indicator system are established to identify the spatial distribution characteristics of street-scale flood vulnerability in Changchun City. The results show that the spatial distribution of flood hazard vulnerability is “high-low-high”, i.e., the vulnerability is higher in the city center and the edge area,and lower in the suburban area. This framework improves the accuracy of the spatial pattern identification of urban flood hazard vulnerability and provides a scientific basis for urban disaster prevention and mitigation planning.

Research on the local compressive bearing capacity of spiral stirrup concrete under crushing failure mode

MIAO Tianming;JIANG Deyu;WANG Bo;

To investigate the local compressive bearing capacity of spiral stirrup concrete under the crushing failure mode, taken 16 local compression tests. it investigated the influences of various local pressure area ratios, concrete strength grades, stirrup spacings, and stirrup diameters on the local compressive bearing capacity of the concrete specimens. The experimental results demonstrate that the local compressive bearing capacity increases as the stirrup spacing decreases, as the local pressure area ratio decreases, and as the stirrup diameter increases, while also exhibiting an upward trend in relation to the concrete strength grade. Based on these findings, a computational formula for local compressive bearing capacity under crushing failure modes was derived and subsequently validated against collected data. The comparison between the model fitting and the gathered data indicates that the proposed formula possesses a high degree of accuracy, effectively predicting the local compressive bearing capacity of spiral stirrup concrete in the context of crushing failure.

Research on optimization of excavation and support scheme for high water content soft soil tunnel——taking a hydropower station in the Middle East as an example

YANG Xiaohua;WANG Ya;LUO Xiaoqin;DU Tiantian;GUO Hong;JIANG Hong;

Taken the tailwater tunnel project of a pumped storage power station in the Middle East as the research object. In response to the difficulties of tunnel excavation and support under high water content soft soil conditions,FLAC3D software was used to numerically simulate the stability of surrounding rock under different support conditions and optimize the support scheme. The development of stress field, displacement field, and plastic zone of surrounding rock was also analyzed. The research results indicate that with the strengthening of support measures, the vertical and horizontal displacements of the tunnel are significantly reduced, the distribution of maximum and minimum principal stresses tends to be reasonable, and the plastic zone is effectively controlled. The support effect of pipe shed+anchor rod+steel arch is the most significant, and the support effects of pipe shed+steel arch and pipe shed+anchor rod+steel arch are similar, with obvious economic benefits, which can be used as a recommended support scheme for the project. This method has important guiding significance for the design, construction, safety and economic research of high content water soft soil tunnel engineering.

Study on optimum design of mix ratio of polypropylene fiber cement based composite material

YU Haonan;LI Hanjun;ZHAO Jing;LIU Jiarui;WANG Wensheng;

The response surface design method was used to study the effects of water cement ratio, sand cement ratio, and fiber volume fraction on construction and workability of polypropylene fiber cement-based composite materials. Furthermore, the orthogonal experimental design method was used to analyze effects of silica fume content and fiber volume fraction on mechanical properties of cementitious materials with embedded colloids. The correlation coefficients R2 of surface model for the influence of slump and expansibility are 0.957 6 and 0.958 7,confirming the reliability of response surface design method. The results show that the water cement ratio had the most significant impact on the construction and workability of polypropylene fiber cement-based composite materials, the P-values of the water cement ratio in the ANOVA were all less than 0.000 1, and compared to the results of the extensibility test, the sand cement ratio and fiber volume fraction had a more significant impact on slump. The optimized mix proportion of polypropylene fiber cement-based composite material is as follows, water cement ratio of 0.3, sand cement ratio of 0.8, silica fume content of 90 kg, and fiber volume content of 1.5%.

Study on the perforation desian of segmented buckling-restrained brace internal core plates

GUO Chengxin;XU Shuai;

Based on Abaqus finite element simulation, in-depth research is conducted on a segmented buckling restrained brace to improve its energy dissipation performance. The study meticulously examines the hysteretic behavior of these bracing systems by adjusting the orifice size and the positional coordinates of the apertures.The results of the study suggest that when the middle aperture and position remain unchanged, the closer the opening position is to the ends of the internal core plate, the higher the likelihood of buckling failure and deformation, resulting in greater displacement and stress of the internal core plate. Conversely,when the openings on both sides are closer to the middle of the internal core plate, the area of the hysteresis ring becomes larger, and the energy dissipation capacity becomes stronger. In addition, the study found that when the hole diameter and position of both sides remain constant, the larger the middle hole diameter of the internal core plate, the greater the anti-buckling stress and deformation, the smaller the hysteresis ring area,and the poorer the performance. Optimal selection of the initial position and orifice diameter can significantly enhance the energy dissipation efficacy of the bucking-restrained brace.

The Cause of Global Warming

WANG Hong-jie,SONG Xiao-dong,WANG En-shi(Jilin Institute of Architecture and Civil Engineering ,Changchun ,China 130021;

In the early 1930s ,the distinguished Yugoslavian climatologist Milankovich had already developed the theory that a tiny ? uctuation in the eccentricity ratio of Earth's orbit ,or the obliquity of Earth's spin axis ,even in the position of the first point of Aries may render a direct in? uence on the solar radiation's range and degree;therefore ,causes the climate change on Earth .Based on a comprehensive calculation ,the authors came to the conclusion that besides the robust increase of greenhouse gases(CO2 ,CH4 ,etc .) , there are also other factors that cause global warming , but this paper focuses on the angular change between Earth's axis and its ecliptic plane .According to the paper ,both the internal variables(earthquake ,wind ,tide ,rocket's launching ,etc .) and the external variables(the sun's motion , other planets' motion ,meteoric stone ,etc .) impacted greatly on this angle .What's more ,no matter to what degree this angular change arrives at ,it inevitably causes the climate change on Earth throughout the time .
