摘　　要：辽宁省铁岭市广裕路北道口立交桥南引道距离某居民楼仅2.0 m左右,引道挡土墙基础无法采用明挖方案,经诸多方案比较,设计采用高压旋喷注浆营造挡土墙方案。介绍了该工程旋喷挡土墙施工工艺及其施工效果。The southern ramp of the Beidaokou overpass is only 2.0m from the resident building at Guangyu Road,Tielin,Liaoning,which makes it impossible to construct the retaining wall with open excavation.Through comparison of various alternatives,the jet-grouting method is adopted.This article describes the jet-grouting process and its benefits.
