唐山市岩溶塌陷的神经网络预测模型

Neural network predicting model of karst collapse in Tangshan city

唐山市多次发生岩溶地面塌陷,造成建筑物破坏。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。岩溶塌陷的产生受多种因素影响,塌陷预测的关键是找到各种影响因素与岩溶塌陷的关联关系。应用人工神经网络方法建立了岩溶塌陷预测模型。分析了计算结果,并对城市规划建设提出了几点建议。

Many karst collapses have happened in Tangshan city, which destroy lots of buildings. Karst collapses are very dangerous geological disasters. They not only destroys buildings and human environment also endanger the safety of life when they take place in urban areas. Karst collapse is controlled by many factors, so the associated relations between collapse and influence factor is the key to collapse prediction. By application of neural network method, predicting model of karst collapse is constructed. The calculated results are analyzed, and some suggestions for city construction are given.
