Stability Analysis and Support Research of Soil-rock Composite Deep Foundation Pit
In the area with complex geological conditions,the stability of soil-rock combined deep foun dation pit engineering is related to the quality of the project,which needs to be studied emphatically.In view of this,this paper deeply analyzes the stability and supporting technology of soil-rock combined deep foundation pit,and discusses the applicability of different soil-rock slope failure modes and supporting struc ture schemes.Based on the calculation and analysis of lateral earth pressure,rock pressure and lateral rock-soil pressure of a foundation pit project,two supporting schemes of'single row pile+prestressed anchor ca ble'and'upper anchor retaining wall+lower double row pile'are compared and analyzed.The results show that for the geological conditions of soil-rock combination with middle rock mass,the support of'upper anchor retaining wall+lower double row pile'can provide better stability.
