考虑耦合作用的建筑深基坑支护施工技术分析

Analysis of Construction Technology for Deep Foundation Pit Support Considering Coupling Effect

由于建筑深基坑支护经常发生变形和位移现象,起到的支护效果较差,为此提出考虑耦合作用的建筑深基坑支护施工技术分析。在充分考虑建筑深基坑应力、围岩结构等影响因素的基础上,利用有限元软件对建筑深基坑支护施工数值模拟,确定建筑深基坑支护结构支护长度和距离,使支护在强度、刚度和结构上达到完全耦合,从而提高建筑深基坑支护强度。

Due to the deformation and displacement phenomenon of deep foundation pit support,the supporting effect is poor.Therefore,the construction technology analysis of deep foundation pit support considering coupling effect is proposed.On the basis of fully considering the influence factors such as the stress of building deep foundation pit and surrounding rock structure,this paper uses the finite element software to simulate the construction of building deep foundation pit support,determines the support length and distance of building deep foundation pit support structure,so as to achieve complete coupling of support strength,stiffness and structure,so as to improve the support strength of building deep foundation pit.
