摘要
结合工程实例,分析了深基坑支护结构设计方法;采用二维和三维分析方法计算支护结构的内力、变形等,并将两者的结果进行了比较,验证了模型的合理性以及平面结合整体计算方法的可行性。运用整体计算分析把握总体设计概念,并结合二维平面分析计算支护桩的整体稳定、抗倾覆、抗隆起、管涌验算和截面设计。
Based on an excavation case,the design methods of deep foundation pit supporting system are analyzed;the inner forces,deformations are calculated by 2D and 3D models,and the results of these two models are compared.Therefore,the reasonableness of two models and the feasibility of calculation method of the plane combined with the overall are verified.Holding overall design concept by using overall calculation analysis,the whole stability,antidumping,resisting upheaval,piping and section design of the support pile are calculated combined with 2D analysis.
