摘要

渗压效应是指由于降雨入渗补给岩溶地下水，而对盖层土体产生的综合作用，包括静水增荷效应、垂直渗透效应、吸水软化效应及负压封闭效应。渗压效应致塌机制是多年持续采水区降落漏斗中心部位岩溶塌陷的主要力学机制。本文根据普氏理论及极限平衡理论分别建立了内部塌陷阶段临界土洞的高度表达式及地表塌陷阶段的渗压效应致塌力学模型，并用表达式及模型对枣庄市的岩溶塌陷进行了验证分析与评价，分析结果与实际塌陷情况符合较好，建立的表达式与模型基本上反映了该地区岩溶塌陷的形成机理。

Abstract

The seepage pressure effects are comprehensive actions on cover-layer in the process of rain feeding karst groundwater

which includes load-increased effect of water

vertical-seepage effect

wetting-soft effect and obturation negative-pressure effect. And the seepage pressure mechanism is the primary mechanism of karst collapse in the center of cone of depression in continual pumping region. Based on the theory of М•М•Протодьяконов

the limit equilibrium theory and the karst collapse law in Zaozhuang city

this paper has established the mechanical model of surface-collapse phase and determined the height of equilibrium soil-hole in inter-collapse phase. Meanwhile

an evaluation of karst collapses in Zaozhuang city has been carried out by means of the formula and mechanical model. The result shows that the formula and mechanical model coincide with the forming mechanism of karst collapse in Zaozhuang city.
