近年来,城市高层建筑迅速发展,和基础埋置深度的加大给施工带来了困难,尤其是在建筑物密集的市区,地下管线多,周围环境复杂,基础施工很少有可能采用大开挖的方法,必须要在人工支护的条件下进行基坑开挖,才能使工程顺利进行。因此,如何结合工程实际,使支护结构建立在科学合理 In recent years, the rapid development of high-rise buildings in cities and the increase in the depth of foundation burial have brought difficulties to construction. Especially in densely-constructed urban areas, there are many underground pipelines, and the surrounding environment is complex. Basic construction is rarely possible. The method of excavation must be excavated under the conditions of artificial support in order to make the project proceed smoothly. Therefore, how to combine the actual conditions of the project so that the supporting structure is established in a scientific and rational way
