摘要
当今城市建设的发展已向立体三维展开,地下工程纵横交叉,新建地铁工程深基坑的开挖面临上下左右已建建筑基础、地下管线、高架桥和多条地铁等设施的保护要求。结合上海轨道交通在运营地铁1号线小半径曲线运营区间隧道旁的深基坑开挖实践,介绍了上海地区控制深基坑变形,保护周边设施的方法和技术。
Nowadays, the development of city construction has been carried out in a three-dimensional way, and the surroundings of underground constructions have been more complex than before. It is inevitable that some deep excavations of metro stations being carried out in a complex surrounding, where all kinds of existing underground projects are adjacent, and their protection requirements are very strict. The practice of a deep excavation project which is adjacent to the shortest-radius curved segment of Shanghai No. 1 operating metro tunnel is used to illustrate the measures of how to control the deflection of deep excavation to protect the adjacent projects in Shanghai.
