摘　　要：苏州工业园区木沉港泵闸及水立交工程,在娄江河下部采用水立交的方式布设一个引清通道,在娄江河南北两侧布设始发井和接收井二个沉井。文章通过对沉井天然地基进行承载力验算,得出了需要对地基进行处理、采用砂垫层的施工方案。本工程案例可为其他类似工程提供参考,从而起到保证工程质量和安全,杜绝安全事故的作用。The water interchange layout is adopted to set a clear water diversion channel in the lower part of the Loujiang River in Suzhou Industrial Park Muchengang Pump Gate and Water Interchange Project.Two open caissons,an initial caisson and a receiving caisson,are arranged in the north and south sides of Loujiang River.The construction scheme requiring foundation treatment and sand cushion layer is obtained by checking and calculating the bearing capacity of the open caisson natural foundation.This project case can provide reference for other similar projects,thereby ensuring the quality and safety of the project,and eliminating the role of safety accidents.
