以安顺市中心城市规划区作为研究对象,收集、综合分析研究区有关地质资料,结合实地调查、物探、钻探、监测、高精度遥感解译等成果,选取6个一级评价因子,15个二级评价因子,建立研究区基于两级模糊数学综合评判法的岩溶塌陷危险性评价方法体系。在此基础上,量化各级指标及权重取值,开展研究区岩溶塌陷危险性评价。结果显示,安顺市中心城市规划区内总体岩溶塌陷危险性中区和高区所占比重较大,占研究区总面积的70.35%,危险性高区主要分布于头铺—幺铺一线,占研究区总面积的13.56%。评价结果与岩溶塌陷历史事件相符,具有较高的可信度。 |
英文摘要: |
In this paper, the urban planning area is taken as the objective, by collect and analysis the relative geologic information, with the results of field investigation, geophysical prospecting, drilling, monitoring and high precision Remote sensing, 6 first-class evaluation factor and 15 second-class evaluation factor are selected, the karst collapse risk evaluation system which is based on two-level fuzzy mathematical comprehensible evaluation method is founded. So the different norms and weights are quantized, the karst collapse risk in the studying area is assessed. The result shows the proportion of middle and high risk in the urban planning area is big (70.35% of the total area), the high risk area mainly distributed in the Toupu-Yaopu line (13.56% of the total area), the results are consisted with the karst collapse history events and believable. |
