Abstract: Based on a project of Shenyang, the digging pile compressive spins with the methods-the static load test, hole-diameter test, pile force and the application ofpile body completeness measured data are tested. Super-long pile with the vertical compressive load transfer mechanism and the lateral resistance of deeply "mud wrap gravel" of Shenyang city are studied.
Keywords: large diameter and swivel-driven pile; pebbly soft clay; stress test; branches and plates effect; vertical load capacity
