摘要
在已有的车站及地下连续墙的二维有限元模型基础上,针对地下连续墙不同刚度对主体结构的影响进行研究,深入分析了既有深基坑地下连续墙的刚度对车站结构设计内力及实际配筋的影响,按使用阶段结构受力的最不利荷载组合情况的极限包络建立模型。利用有限元软件计算分析地下连续墙考虑不同刚度时与车站结构协同受力情况,对包括地下连续墙在内的围护结构共同作用进行优化设计,可有效提高材料利用率,节约社会资源。
Based on the existing two-dimensional finite element model of the station and the underground continuous wall,the effect of the different rigidity of the underground continuous wall on the main structure was studied,and the internal force of the existing deep foundation pit underground continuous wall on the station structure design was deeply analyzed with the effect of actual reinforcement.The model is estab-lished according to the limit envelope of the most unfavorable load combination of the structural stress dur-ing construction.The finite element software is used to calculate and analyze the cooperative force of the underground diaphragm wall with the station structure when different stiffnesses are considered,and the op-timal design of the interaction of the envelope structure including the underground diaphragm wall can ef-fectively improve the material utilization rate and save social resources.
