Method for testing geological disaster susceptibility of highway slope in loess area based on time sequence
The invention provides a loess area road slope geological disaster susceptibility test method based on a time sequence, and the method comprises the steps: carrying out the initialization of a test object and an evaluation factor, and determining a geological disaster susceptibility evaluation factor; calculating the weight of each evaluation factor by using an analytic hierarchy process, and carrying out iterative optimization until the consistency test index CR is globally minimum; dividing the interval grades of the evaluation factors, calculating the information amount corresponding to each interval, and comprehensively obtaining the information amount of the single slope; calculating the AUC value of the evaluation result, and adjusting and optimizing the interval grade division of the evaluation factor until the evaluation result is relatively optimal; and delimiting a susceptibility evaluation interval according to an evaluation result, and determining a slope evaluation grade. Through the method, the logicality of judgment matrix construction in the analytic hierarchy process can be improved, the reasonability of evaluation factor interval division in information amount calculation is reduced, the influence of human subjective factors on the evaluation process is reduced to the maximum extent, and the objectivity, fairness and accuracy of an evaluation result are improved.
本申请提供了一种基于时间序列的黄土地区公路边坡地质灾害易发性测试方法，包括：对测试对象和评价因子进行初始化，确定地质灾害易发性评价因子；利用层次分析法计算各评价因子的权重，并迭代优化直到一致性检验指标CR达到全局最小；划分评价因子的区间等级，计算各区间对应信息量，综合得到单体边坡的信息量；计算评价结果的AUC值，调整优化评价因子的区间等级划分，直到评价结果相对最优；根据评价结果划定易发性评价区间，确定边坡评价等级。通过该方法能提高层次分析法中判断矩阵构建的逻辑性，降低信息量计算中评价因子区间划分的合理性，最大程度降低人为主观因素对评价过程的影响，提升评价结果的客观公正和准确性。
