According to the Hefei subway deep foundation pit engineering,
this study expounds the pile-anchor supporting scheme of prestressed anchor
cable layout optimization. Combined with the actual situation of engineering,
numerical simulation was carryed out by using FLAC3D software. The four different
layout of prestressed anchor cable is used for simulation analysis, Detailed
to carry out the horizontal displacement of the pile and anchor axial force
analysis, discuss the anchor cable layout optimization. Calculation results
provide a reference for support scheme of similar large deep foundation pit.
