随着我国社会经济的快速发展,建筑行业也取得了很大的进步,尤其是近些年高层建筑和超高层建筑的大力兴建,使得深基坑支护技术被越来越广泛地应用到施工过程当中,可是在具体应用过程总是容易出现变形问题,施工企业为了更好地确保整个工程施工进度的顺利推进,并尽可能减少对周围建筑物的影响,更好地确保整个工程的安全稳定性能,就必须在基坑开挖的时候,对其坑底回弹隆起和地面下沉问题引起足够的关注,避免支护结构发生坍塌现象。鉴于此,本文先分析了基坑变形的种类和问题,并阐述了变形监测的目的和具体方法。
With the rapid socio-economic development in our country, great progress has been made in the construction industry. In particular, the vigorous construction of high-rise buildings and super-tall buildings in recent years has made the application of deep foundation pit support technology more and more widely applied During the process, however, deformation problems always occur during the specific application process. In order to better ensure the smooth progress of the entire project construction and minimize the impact on the surrounding buildings, the construction enterprises should better ensure the safety and stability of the entire project Performance, it is necessary in the excavation of the pit, the pit bottom bulge and ground sinking caused enough attention to avoid the collapse of the supporting structure. In view of this, this article first analyzes the types and problems of foundation pit deformation, and expounds the purpose and specific methods of deformation monitoring.
