| 摘 要： | 为了有效预测、预防岩溶陷落柱突水，通过实际资料的水文地质背景分析，以及“厚壁筒”力学模型的模拟，研究了突水形成的基本条件。研究表明，陷落柱的充水受多种条件和因素的控制和影响，适当的水文地质基础是其突水的必要条件，但真正形成突水还必须满足突水的充分条件，即达到或超过力学临界状态，这就决定了绝大部分华北岩溶陷落柱并不充水，一般也形不成突水。

| Abstract: | For water inrush from karstic collapse columns being effectively forecasted and prevented, basic conditions of water inrush forming are studied with analyzing of hydrogeological background in practice and modeling with thick wall cylinders' in mechanics.The results show that properties of water-bearing in karstic collapse columns are controlled and influenced by several conditions and factors, proper hydrogeological basics make up of necessary condition of water inrush, but water inrush happens in deed, there must be sufficient condition being met, namely, critical mechanics states being reached or exceeded.That is why most of them don't bring on water inrush disaster in normal situation. |
