摘要
对深基坑支护的方案设计、成孔工艺、影响因素及环境保护进行了分析,总结出一套深基坑支护在地下人防中的技术经验,提出了对垂直渗透系数较小,但水平渗透系数较大的湿陷性黄土的支护方法,对今后类似地质条件施工降水具有一定的参考价值。
This paper analyzed the scheme design,pore forming process,influence factors and environmental protection of deep foundation pit support,summarized a set of technology experience of deep foundation pit support in underground civil air defense,proposed the collapsible loess support method had small vertical permeability coefficient,but larger horizontal permeability coefficient,had certain reference value to future similar geological conditions construction lowering.
