The Application of Pile and Shotcrete Anchor Supporting in a New Station Building Deep Foundation Pit in Rock and Soil
摘要
Abstract
Based on the analysis of the characteristics of deep foundation pit in rock and soil, the pile and shotcrete anchor supporting is recommended for those deep foundation pits in rock and soil in complex surrounding environment with medium hard or hard lower part rock. And three-stage calculation is conducted for design calculation. For a new station deep foundation pit in soil and rock, three-stage calculation method is used for pile and shotcrete anchor support design, and numerical simulation is used for analysis. The results show that the pile and shotcrete anchor supporting can effectively control the pit deformation and ensure overall stability of the deep foundation pit. So it is verified that the shotcrete anchor support is suitable for deep foundation pit in rock and soil and the three-stage calculation method is safe and reliable.关键词
