摘要
软土地基深基坑一般采用内撑式排桩(地下连续墙)支护结构,相邻基坑在相同或相近时间开挖,会产生相互影响。通过理论分析和工程实践,提出了顶部冠梁通过连杆相连的措施,可以确保各自支护结构的稳定性;通过有限元计算并通过实测对比,阐明了相互影响规律,取得了良好效果。
Deep foundation pit in soft soil foundation is usually supported by inner supporting piles(diaphragm wall). Excavation of adjacent foundation pits at the same or similar time will affect each other. Through theoretical analysis and engineering practice,this paper puts forward the measures of connecting the top crown beam with connecting rods,which can ensure the stability of each supporting structure.Through the finite element calculation and comparison with the actual measurement,the law of mutual influence is clarified,and good results are obtained.
