摘要
本文通过大量工程的野外调研和岩溶塌陷数据资料分析,将覆盖型岩溶发育地区土体盖层岩溶塌陷的数学模型分为导水盖层和阻水盖层两种典型情况。提出了“导水介质覆盖层的渗流场—应力场耦合的数学模型”和“阻水介质盖层的渗流场—强度弱化—压差场数学模型”。针对模型的数学物理意义进行了探讨并提出了建立“岩溶塌陷数学模型系统”的基本设想。
This paper discussed two typical collapses in permeable and impermeable cap soils at the covered karst area through quantitative field investigations and data analysis, and develops corresponding mathematical models of coupling seepage field with stress field and interaction of seepage field-the weakness of strength-barometric pressure respective-ly in accordance with the above cases. The mathematical and physical significance of the models are discussed and the fundamentality of establishing the mathematical models sys-tem of collapse is given in the paper.
