随着城市建设的不断发展,超高层建筑及深基坑项目在工程勘察中常遇到。特别是在城市中心建设标志性建筑。地下空间已被城市交通建设利用,如地铁、轻轨等交通枢纽。为此;在工程勘察中常常会遇到附有深基坑及周边隧洞影响的建设项目。本文以重庆市某大厦勘察为例,介绍深基坑在工程勘察中的评价及对周边隧洞的相互影响评价,本项目勘察成果取得了较好的效果,为项目的设计、施工提供了指导性的基础资料。
With the continuous development of urban construction, super high-rise buildings and deep foundation pit projects often encountered in engineering investigations. Especially in the city center building landmark. Underground space has been the construction of urban traffic utilization, such as the subway, light rail and other transport hubs. To this end; often encounter in construction projects with deep foundation pit and the surrounding tunnel construction projects. Taking a survey of a building in Chongqing as an example, this paper introduces the evaluation of deep foundation pit in engineering investigation and the mutual influence evaluation of surrounding tunnels. The survey results of this project have achieved good results and provided guidance for the design and construction of the project The basic information.
