摘　　要：本工程翻车机房围护工程截渗设计中首次在抛石堤中采用柔性地连墙和高压帷幕灌浆相结合的防渗结构;另外,本工程在设计中不照搬以往类似工程的设计,还对圆形地连墙圈梁、竖肋、廊道地连墙水平支撑、曲腰梁等进行了优化设计,缩短了工期,降低了工程造价,产生了可观的经济效益,可供今后类似工程借鉴。The combination of flexible diaphragm wall and high-pressure curtain grouting serves as an anti-seepage structure,which is adopted firstly in the retaining works for car dumper shed,i.e.riprap dike.In addition,an optimal design is made for ring beam and vertical rib of circular diaphragm wall,horizontal support and curved waist beam of corridor’s diaphragm wall based on the design experience in similar projects.This design optimization can shorten construction period,reduce project cost,produce considerable economic benefit and provid a references for similar projects in the future.
