| 摘 要： | "一桩两用"技术是在基坑开挖过程中通过桩墙合一技术将排桩支护结构体系与地下室外墙形成复合结构,共同抵抗土压力。在盖挖逆作法施工中采用"一桩两用"技术,不仅可节约大量费用,而且使地下结构的外墙的受力状态更为合理。文中结合工程实例,应用大型通用有限元工程分析软件ANSYS根据弹性地基梁法对桩墙合一的复合结构进行了力学分析。

| Abstract: | The application of dual-purpose pile is a technique in which retaining piles are combined with outer walls of substructures to resist the earth pressure.The application of dual-purpose pile in topdown construction can not only save costs,but also make the mechanic condition of substructure walls more rational.Based on real construction,this paper uses ANSYS to calculate the mechanic features of the combination of retaining piles and substructure walls during different construction stages.This paper calculat... |
