Abstract
To solve the issue of missing economically reasonable parameters in the design process of Larssen steel sheet pile support under limited construction space conditions in pump stations,which often relies on engineering experience to determine design parameters and verify the safety of the support structure,the Larssen steel sheet pile supports of Shengwei drainage sta-tion in Fanchang District,Wuhu City was identified as the key parameters for steel sheet pile design,including pile length,spacing between supports,and distance between supports and the pile top.Based on Midas XD software,the elastic pivot method,control variable method and other methods were used to optimize key parameters by analyzing the safety factors of em-bedded stability,anti uplift stability,and surge stability,pile bending moment,maximum horizontal displacement of pile body,and maximum surface settlement around the foundation pit.The optimal parameters using this method were as follows:steel sheet pile length of 18 m,spacing between supports of 3 m,and distance between supports and pile top controlled within 2～3 m.This method conducted multiple safety tests on key parameters to obtain the optimal engineering values,which reduced the dependence on engineering experience in the design process and provided relatively economical and reasonable parameter re-sults,providing reference for parameter optimization design similar to steel sheet pile support.关键词
