摘要
喀斯特塌陷是某新建国际机场建设面临的最主要工程地质问题。根据工程区实际情况,选取3个条件层的15个因子构建喀斯特塌陷预测模糊层次模型,确定各因子的权重;采用模糊数学方法,以MapGIS为平台,对含有不同权重的各因子进行空间迭置分析、计算,来确定、划分工程区喀斯特塌陷的危险性分区。现状下,喀斯特塌陷绝大部分处于危险性中等区和危险性大的范围内。预测评价结果客观可靠。
The karst collapse is the most important engineering geologic problem a faced by new international airport, so a research on the assessment of the karst collapses predetermination is necessary. According to the state of the building region, 15 factors belonging to 3 conditions-layers are chosen to construct the assessment model of the karst collapses predetermination using the fuzzylayer model, then, to determine the weight of the different factors and depict the influence of the different factors to the karst collapses, and later, to assess the effect of the different factors using fuzzy mathematics and MapGIS to analyse and count space-laminated-construction formed by the different factors with different weights. Finally, the karst collapses dangerous zone is determined. At present, most of the karst collapses lie in the middle-rank dangerous zone and great-rank dangerous zone . The assessment result is objective and reliable.
