Numerical Simulation Analysis of Composite Soil Nailing Wall in Deep Foundation Pit with Inclined and Straight Steel Pipe Piles
Based on a foundation pit project in a hospital in Fuzhou,the numerical simulation method was adopted to study the deformation characteristics and stability of composite soil nailing wall with inclined and straight steel pipe piles.The result shows that the maximum deformation of horizontal displacement of the slope surface occurs at the"waist"position of the foundation pit,the deformation control of this position should be properly strengthened during designing.The supporting system of composite soil nailing wall with inclined and straight steel pipe piles is safe and feasible,and has better ability of deformation control and higher stability compared to composite soil nailing wall with double rows of vertical steel pipe piles or single form of soil nailing wall.
