摘要
本文根据土力学和结合水动力学原理 ,在以往所建模型的基础上 ,建立承压、承压变负压、负压条件下的 3个坛状圆柱状岩溶塌陷预测模型 ,对塌陷预测模型进行了分析与检验 ,结果表明 ,这些模型可以用于岩溶塌陷预测。
According to soil mechanics, boud-water dynamics and previously established models,three forecast models are established for karst collapse shaped in jar or column under the conditions of pressure,negative pressure,the pressure changing from the above pressure to negative pressure.These models are analysed and checked by concrete instances.The checking results show that these models can be used in karst collapse forecast.Finally,these models are trially used to forecast the karst collase of a certain soil cave in Guilin.
