基坑渗流稳定分析

Analysis on Seepage Stability of Foundation Pit

在透水性较强的地层中,基坑渗流稳定是保证基坑安全的重要因素之一。结合清明上河园地下停车场基坑工程,研究渗流对基坑安全稳定的影响,及渗流情况下基坑稳定的判别、分析计算方法。对影响基坑渗流的一些因素进行了探讨,提出了基坑渗流稳定分析的控制原则,提出了控制基坑渗流稳定的工程措施和建议。

The seepage stability is an important factor to insure the safety of the foundation in a strong permeability formation.Combined with the foundation pit engineering of Qingming River Park＇s underground parking area,the effect of seepage to the safety and stability of the foundation pit is studied,and the discrimination and analysis methods for the stability of the foundation pit are studied with the consideration of seepage effect.Simultaneously,the factors effecting the foundation pit seepage are discussed,and the control principle for the analysis of foundation pit seepage stability is put forward.At last,the engineering measures and suggestions to control the seepage stability of foundation pit are proposed combined with engineering projects.
