由于在中心城区轨交沿线开工的深基坑工程日益增多,所以确保周边环境的安全,尤其是轨交的正常运营,是深基坑施工中需首要考虑的问题。通过总结临近轨交的深基坑施工成功的经验,从主要施工阶段的控制要点着手,采取技术应对措施,控制了基坑变形,确保了周边环境的安全及轨交的正常运营。
Due to the increasing number of deep foundation pit works started along the intersection of central urban area, ensuring the safety of the surrounding environment, especially the normal operation of rail transit, is the most important consideration in the construction of deep foundation pit. By summing up the successful experiences of the construction of the deep foundation pit near the rail intersection, the paper starts from the control points in the main construction stage and takes technical measures to control the deformation of the foundation pit to ensure the safety of the surrounding environment and the normal operation of the rail crossing.
