| 摘 要： | 岩溶塌陷是一种危害性很大的地质灾害，发生在城市的岩溶塌陷不仅破坏人类的生存环境，毁坏建筑物，而且危及人民的生命安全。岩溶塌陷稳定性评价的关键是找到各种影响因素与岩溶塌陷的关联关系。通过分析岩溶塌陷的成因与主要影响因素，介绍了应用人工神经网络方法的计算步骤。以唐山市为例，建立了岩溶安全性评价模型，预测了唐山市岩溶塌陷稳定性分布。分析了计算结果，并对城市规划建设提出了几点建议。

| Abstract: | Karst collapse is a very dangerous geological disaster. It not only destroys the buildings and environment but also endangers the safety of life when it takes place in urban. The associated relationship between collapse and influence factors is the key of safety evaluation. By analyzing the mainly influence factors of karst collapse, the calculating steps of neural network method is introduced. As an example of Tangshan city, safety evaluation model of karst collapse is constructed. The calculating results are analyzed and some suggestions for city construction are given. |
