随着城市建设的发展,高层建筑越来越多。随着建筑高度增加,根据构造及使用要求,基础埋深也随之不断增加,这样就出现了大量的深基坑工程。且城市基坑工程往往处于房屋和生命线工程的密集地区,很多情况下不允许采用比较经济的放坡开挖,而需要在人工支护条件下进行基坑开挖。为了保证基坑周围的建筑物、地下管线、道路等的安全,应大力研究深基坑支护技术。本文现就淮北市水岸·国际广场工程深基坑施工中复合土钉墙的应用作了探讨总结。
With the development of urban construction, more and more high-rise buildings. With the increase of building height, according to the requirements of structure and use, the basic buried depth also increases continuously, so a lot of deep foundation pit projects appear. In addition, urban foundation pit projects are often located in densely-populated areas of houses and lifeline projects. In many cases, it is not allowed to adopt more economical grading and excavation, and the excavation of foundation pit needs to be carried out under the conditions of artificial support. In order to ensure the safety of buildings, underground pipelines and roads around the foundation pit, deep excavation support technology should be studied. This article is on the Huaibei City Waterfront International Plaza project deep foundation pit construction of composite soil nailing wall made a summary.
