摘　　要：为满足顶管施工对施工效率和施工精度的需求,避免进出洞周围出现土体流失以致周围路面及附近管线损坏的现象,采用沉井施工技术加固洞口土体,加固范围根据实际效果调整,防止造成下沉过程中对井壁的抱死。研究结果表明:在顶管工程中成功应用沉井施工技术,可有效解决管道埋设施工对既有建筑的破坏和道路交通堵塞的难题,值得大范围推广应用。In order to meet the requirements of construction efficiency and accuracy in pipe jacking construction,avoid the soil loss around the entrance and exit holes and damage to the surrounding pavement and pipelines,the caisson construction technology is used to reinforce the soil at the entrance of the caisson,and the reinforcement scope is adjusted according to the actual effect to prevent the lock of the shaft wall in the process of sinking.The results show that the successful application of caisson construction technology in pipe jacking project can effectively solve the problems of damage to the existing buildings and the road traffic jam caused by pipeline burying facilities,and is worthy of wide application.
