某临近铁路的排水泵站深基坑支护方案优化

Supporting Scheme Optimization of Deep Foundation Pit of A Drainage Pumping Station Nearby Railway

通过对临近铁路干线的深基坑支护作业不利的环境及地层地质情况的分析,提出了该基坑的优化和替代方案以及施工工艺优化,支护设计采用《理正深基坑支护》F-SPW6.0版软件计算,适当加大安全系数,确保临近铁路的运行安全,为类似的基坑支护设计、施工提供借鉴。

In this paper, through the analysis of the adverse environmental and geological condition of deep foundation pit support- ing operations in adjacent railway lines, the foundation pit optimization and alternatives and optimization of construction technology are put forward, ＂leading＂ version of the F - SPW6. 0 software is applied to calculate the supporting design of deep foundation pit, and higher safety factor could ensure the safe operation of appropriate, provide the reference for the similar foundation pit support design, construction.
