小空间深基坑支护方案的优化设计

Optimal Design of Deep Foundation Pit Supporting in Small Space

以唐山某工程为例,通过分析施工场地条件,合理选择基坑支护方法,使基坑支护施工具有可操作性,通过优化设计,达到基坑支护目的,缩短了工期,节约了成本,同时介绍了微型钢管桩施工工序各环节的质量控制及提高桩体强度的办法,为今后此工法施工提供借鉴。

This paper takes a project in Tangshan as an example, by analyzing the condition of construction site,reasonable selection of foundation pit supporting method,makes the foundation pit supporting con-struction can be operable. By optimizing design,to achieve the purpose of foundation pit supporting, short-en the construction period,cost savings. At the same time, it describes various aspects of micro steel pipepile construction process quality control and measures to improve the strength of pile body, to provide ref-erence for the construction for the future.
