复杂周边环境下深基坑的施工技术研究

Study on Construction Technology of Deep Foundation Pit in Complex Peripheral Environment

本文以某医院新病房综合大楼基坑施工为例,分析项目施工的难点,提出解决思路,并详细介绍了工程中应用的各种先进施工技术,包括高低差处采用钢板桩加固,增设钢筋混凝土斜撑,分区分层土方开挖以及金刚石绳锯、静力切割法配合拆除内撑作业等。

Taking the foundation pit construction of a new ward complex building in a hospital as an example,this paper analyses the difficulties in the construction of the project,puts forward some solutions,and introduces in detail various advanced construction techniques applied in the project,including steel sheet pile reinforcement at the height different areas,reinforced concrete diagonal brace reinforcement,layered earthwork excavation,diamond rope saw and static cutting method combined with the removal of internal brace,etc.
