摘要
在基坑支护方面,传统意义上的斜抛撑需要结合主体结构的布置情况进行设计,受到较多的客观限制,有必要综合斜抛撑支护形式优点的同时也尽量规避其缺点。采用二维有限元软件Plaxis进行有限元数值模拟的方法,研究常规基坑下同期开挖条件下斜抛撑形式的受力性状并进行了经济对比分析。研究结论证明在周边环境不敏感的情况下,同等深度的基坑工程,采用改良后的斜抛撑体系在工程中具有良好的性价比。
In the aspect of foundation excavation support,the traditional slope support needs to be designed in combination with the arrangement of the main structure,which is limited by many objective factors. By means of two dimensional finite element software,Plaxis numerical simulation,the mechanical characters of the slalom support form under conventional excavation are studied and analyzed. The results show that the improved cable-plough system is effective in the construction of the foundation pit with the same depth when the surrounding environment is not sensitive.
