摘要
当不对称支护结构下的基坑采用对称支撑支护形式时,可通过支撑刚度的调整将支护结构简化为对称支撑结构进行计算,给出了具体的支撑刚度调整方法,并以典型基坑工程为背景,对支护结构典型剖面进行了计算,并将计算结果与有限元计算结果相比较,结果验证了该方法的可靠性,更加符合实际。该计算方法可供同类工程参考。
When the deep foundation pit with asymmetric supporting structure is supported by symmetrical supporting type, the calculation of asymmetric supporting structure can be simplified and considered as symmetrical supporting structure by adjusting the supporting stiffness. The method for adjusting the suppnrting stiffness is presented. Taking a typical deep foundation pit project as background, the typical profile of supporting structure is calculated, and calculation results are compared with those by FEM. Resuhs prove that this method is reliable and more close to the reality. This method can give reference In other similar projects.
