顶管施工对周边土体和环境的扰动分析

Pipe Jacking Construction Surrounding Soil and the Environment of Disturbance

顶管施工推进中对周围环境造成影响的因素较多,有顶进中的正面推进力、工具管与土的剪切摩擦力、正负地层损失、顶进中管道与土层间减摩浆液的压力及分布,以及顶进纠偏管与土的剪切力、摩擦力等。因此,分析顶管施工对周边土体和环境的影响对于施工安全很重要。

pipe jacking construction of pushing forward the factors affect the environment around more, have positive role of jacking propulsion, tool tube and soil shear friction, plus or minus strata losses, of jacking interlayers of pipeline and the pressure distribution and antifriction grout, and of jacking rectification of soil shear force tube, friction, etc. Thus, the analysis of pipe jacking construction surrounding soil and the influence of the environment is very important for construction safety.
