摘要
岩溶塌陷是某新建国际机场建设面临的最主要工程地质问题,开展岩溶塌陷易发性预测评价研究十分必要。选取3个条件层的15个因子构建岩溶塌陷预测模糊层次评价模型,确定各因子的权重,刻画各因子对岩溶地面塌陷产生的影响程度及各因子的组合效应;采用模糊数学和MapGIS方法,对含有不同权重的各因子进行空间迭置分析计算,确定工程区岩溶地面塌陷的易发性分区。预测评价结果客观可靠。
The Karst collapse is the most important engineering geologic problem a new international airport faces,the research of assessment of the Karst collapses predetermination is necessary. We choose 15 factors belonging to 3 conditions - layers to construct the assessment model of the Karst collapses predetermination using the fuzzy - layer method, then, we determine the weight of different factors and depict the influence of different factors on the Karst collapses,later , we assess the combined effect of different factors;We use fuzzy mathematics and MapGIS to analyse and count space - laminated - construction, which is formed from different factors, with different weights. Finaly, we determine the Karst collapses zoning. The assessment result is objective and reliable.
