摘要
为了预防和杜绝地铁深基坑渗漏水事故,从水文地质因素、施工因素、水位监测等方面综合分析了渗漏水高发的原因,并着重讨论了深基坑施工中水位监测的作用,提出了水位监测的改进方法和合理的介入时间,并与其他施工相结合,通过综合分析确定渗漏水原因,从而实现早发现早治理,将事故消灭在萌芽之中。
Water-seepage is one of the common and dangerous incidents in the construction of deep foundation pits. In the paper, the causes for the water-seepages are studied in terms of hydrogeology, construction methods and water level monitoring. The effect of water level monitoring in the construction of deep foundation pits is emphatically discussed. Improved methods and timing of water level monitoring are proposed. The practice demonstrates that water seepage incidents can be avoided or can be timely coped with by comprehensive analysis on the water seepage risks.
