随着社会的进步高层建筑的不断兴起,促进了深基坑支护技术的发展。目前城市建筑密集,基坑边缘距已有建筑物间距很小,给工程施工带来很大的难度,也给周围环境带来极大威胁;原来的深基坑支护结构的设计理论、运算公式、施工工艺等不太符合深基坑开挖与支护结构的客观情况,导致一些基坑工程施工事故,造成巨大的损失。
With the continuous improvement of society’s high-rise buildings, and promote the development of deep foundation pit support technology. At present, the urban construction is intensive, and the distance between the edge of the foundation pit and the existing building is very small, which brings great difficulty to the construction as well as great threat to the surrounding environment. The original design theory of deep foundation pit supporting structure, Formulas, construction techniques, etc. are not in line with the objective conditions of deep foundation pit excavation and support structure, resulting in some excavation project construction accidents, resulting in huge losses.
