含填石层滩涂的基坑支护及其施工技术研究

Research on the Foundation Pit Supporting and Related Construction Technology on Mudflat with Stone-Filling Layer

本文以新城立交完善工程的综合管廊基坑支护结构为例,阐述了在含有填石层的海滨滩涂场地上,基坑支护结构类型的比选及钢板桩支护施工关键技术,为以后具备类似地质条件场地的基坑支护结构的设计、施工提供参考。

This paper expounds the comparison and selection of the types of foundation pit supporting structure and the key technologies of steel sheet pile supporting construction on the mudflat site with stone filling layer by taking the foundation pit supporting structure of the comprehensive pipe gallery of Xincheng interchange improvement project in Shenzhen as an example,and aims to provide a good reference for the design and construction of foundation pit supporting structure in similar geological conditions in the future.
