摘要

加筋水泥土桩锚支护体系兼具拉锚支护和土体注浆加固特点,有利于基坑的稳定。首先介绍了其作用原理及其计算方法。水口一号基坑采用加筋水泥土桩锚支护方案,运用有限元分析软件Z-soil对其进行数值分析。数值计算结果和实测值较为符合,证明了该支护体系适用于闽南软土地区的深基坑支护。
Reinforced cement-soil pile-anchor retaining structure have the characteristics of bolt tensioned support and grouting-strengthening soil.it benefits to the stability of foundation pit.The working principle of reinforced cement-soil pile-anchor retaining structure are introduced,and its calculating methods are also presented.Reinforced cement-soil pile-anchor retaining structure was used in Shui-Kou No.1 foundation pit.A numerical analysis was presented using Z-soil FEM software on it.The results from FEM calculation were compared with the in-situ monitoring data,and they coincide well.It is proved the applicability of this retaining structure for deep foundation pit in soft clay in south Fujian area.
