摘要
为保证深基坑工程的建设水平,文章总结了喀斯特区基坑开挖特点和常用支护方式,以某城市高层住宅建筑为研究对象,制订了基坑支护方案和溶洞处理方案,并利用有限元软件建立计算模型,从支护桩位移、基坑坑底隆起变形、周边地表沉降等方面评价了深基坑的稳定性,研究成果可为类似深基坑项目的设计和施工提供理论指导.
Abstract
In order to ensure the construction level of deep foundation pit engineering,this paper summarizes the characteristics of foundation pit excavation and common support methods in karst area.Taking a high-rise residential building in a city as the research object,the foundation pit support scheme and karst cave treatment scheme are formulated,and the calculation model is established by using finite element software.The stability of deep foundation pit is evaluated from the aspects of support pile displacement,uplift deformation of foundation pit bottom and surrounding surface settlement.The research results can provide theoretical guidance for the design and construction of similar deep foundation pit projects.
