摘要
在深基坑工程设计为悬挂式止水帷幕的情况下,为保证坑内大幅度降水时坑外水位的相对稳定,基于现场抽水、回灌试验,建立地下水-止水帷幕共同作用的三维渗流模型,以有效地指导抽-灌一体化设计。实际应用效果表明,抽-灌一体化设计方法对坑外水位控制是有效的,可以确保周边环境的安全。
In the case that the deep foundation pit is designed as a suspended water stop curtain,in order to ensure the relative stability of the water level outside the pit when there is a large amount of precipitation in the pit,based on the field pumping and back-pumping tests,a three-dimensional seepage model under the interaction of groundwater and water stop curtain is established to effectively guide the integrated design of pumping and back-pumping.The practical application effect shows that the integrated design method of pumping and back-pumping is effective for the water level control outside the pit,which can ensure the safety of the surrounding environment.
