钻孔桩与深搅桩咬合支护结构内力及变形分析

Analysis on internal force and deformation of bored pile biting into deep mixing pile

介绍了新型的钻孔桩与深搅桩咬合式复合支护体系在地铁明挖深基坑的应用,并采用弹性杆系有限元法对支护体系的内力及变形进行了分析,将理论值与实际值进行比较,得出实际值比理论值大的结论。

The article introduces the application of new-type bored pile biting into deep mixing pile composite supporting system in subway foundation pit open cut, analyzes its internal force and deformation by using elastic truss finite element method, and concludes that practical value is bigger than theoretical value.
