摘　　要：树根桩法应用于顶管工程中,可以起到保护地下公用管线,确保周边构筑物的安全,同时可以缩短工期、降低工程造价、施工噪音低、社会效益良好,特别对场地狭窄、净空低矮、地下管线密集的工程现场,其优点尤为突出。本文主要针对树根桩法在洋里污水处理厂二期顶管工程中的具体应用进行论述,阐述了树根桩法作顶管工作坑时的理论计算及设计、基本施工工艺及其优点。Appling Root Pile Method in Pipe jacking Engineering, it can protect underground public pipelines and ensure the safety of peripheral construction. And it can reduce construction time, drop construction cost, low construction noise, and the social efficiency is good. And especially to the engineering spot with narrow location, low clearance and crowed underground pipelines, the benefit of it is even more prominent. This paper mainly discuses the practical approach of Root Pile Method in the second - stage pipe jacking engineering Yan- li sewage treatment plant, elaborates the theoretical calculation and design, the fundamental construction craft and the merit of constructing pipe jacking work pit using Root Pile Method.
