摘要
本文对阻水盖层分布区岩溶塌陷的物质基础和成因机制进行了新的思考 ,提出“溶洞充填物潜蚀流动—压差场—盖层失托增荷效应”为阻水盖层分布区岩溶塌陷更普遍的成因机制 ,给出了理想情况下描述阻水盖层中岩溶塌陷的数学模型。
The paper deals with the mechanism of karst collapse in karst area covered by impermeable cap pings in a new train of thought and presents a more objective interpretation of the karst collapse based on “the effect of underground erosion and flowing of filling material in karst cavities pressure difference fieldlosing of support and increasing of load in cappings”. A corresponding mathematical model of the theory is also established.
