摘　　要：以佛山地铁三号线中山公园站岩溶地层深基坑工程为研究背景,针对岩溶地层深基坑渗流通道渗流特性的表征方法开展研究,并对岩溶基坑三种渗漏模式下的渗漏通道进行概化分析,构建岩溶基坑渗漏水力计算模型,基于水力学管道流理论对概化管道等效渗透系数进行定量表征,实现岩溶基坑渗漏通道的定量分析。Taking the deep foundation pit engineering of karst strata of Zhongshan Park Station of Foshan Metro Line 3 as the research background,this paper studies the characterization method of seepage characteristics of seepage channels in deep foundation pits in karst formations,generalizes and analyzes the seepage channels in three leakage modes of karst foundation pits,constructs a hydraulic calculation model for leakage of karst foundation pits,quantifies the equivalent permeability coefficient of generalized pipelines based on hydraulic pipeline flow theory,and realizes the quantitative analysis of leakage channels of karst foundation pits.
