摘要：Foundation pit excavation adopts a widely used method in real projects—cantilever pile supporting, which has the advantages of easy construction, convenience and low cost, etc. The writers use MIDAS GTS software to build the 3D finite unit model to analyze the influences of such facts as excavation step, pipe diameter, center distance of pile. The conclusion shows: The maximum horizontal and vertical displacement of pipelines in the corner of foundation pit is about 1/2 of its center. The pipeline's diameter increases from 0.6m to 1.2m. The horizontal displacement changes little, but the vertical displacement of pipeline is reduced to half of the original.
