摘要
在软土区的基坑支护工程,常需对基坑坑底进行被动土加固设计,但是现行的规范没有给出明确合理的设计方法。本文通过安徽芜湖某基坑工程实例,提出了针对深厚软土区悬臂支护被动土加固高度和宽度的确定方法,同时通过理正深基坑7.0软件进行分析计算和后期对基坑位移沉降监测数据的分析对比,证明了运用该方法对该基坑进行被动土加固设计是成功的、可行的,也为类似工程的设计提供了可供参考的设计方法。
In the soft soil area excavations engineering,the reinforcement design for the excavations bottom is often needed,but the current standards don＇t give the clear and reasonable design method.Through the foundation pit engineering examples in Wuhu of Anhui, the cantilever support passive reinforcement method for the deep soft soil area is introduced to obtain the height and width of the reinforcement. Based on the analysis calculation by using the Lizheng deep foundation pit software 7. 0 and the monitoring data analysis of excavation displacement,it is proved that the said method for the foundation pit passive reinforcement design is successful and feasible which provides the reference design method for the similar engineering design.
