Complex Hole Pile Construction under the Condition of Research on the Influence of the Surface Subsidence

摘要

Hole pile method as an emerging technology has been widely applied to tunnel excavation in the construction of the subway, so the hole pile construction impact on the earth's surface becomes more important. Using finite element software to simulate the Midas GTS - located in the intersection, the road surface settlement during excavation retaining wall of the lower station, roads, the settlement of retaining wall and retaining wall outside surface subsidence, through the analysis of the data to get the influence of excavation on the settlement at the station. And puts forward measures to reduce the surface settlement, the station of the similar excavation engineering has a certain guiding significance.
