摘要
基于距离判别分析理论,选用隧道的埋深、隧道区植被覆盖情况、隧道区年平均降雨量、隧道区地表水状况等8项指标作为距离判别分析模型的判别因子,以调查的数据作为训练样本,建立了隧道渗漏水灾害分级预测的距离判别分析模型,经过训练后的模型回判估计的误判率为零.利用该模型对国内圆梁山隧道和西奇一号隧道渗漏水情况进行预测,结果与实际符合,说明该模型在研究隧道渗漏水发生可能性及分级预测中有良好的实用性.该方法为隧道渗漏水灾害分级预测提供了一条新思路.
The prediction of possibility and classification of tunnel leakage are important issues in the process of tunnel construction and operation.Based on the principle of Mahalanobisdistance discriminant analysis(DDA),a distance discriminant analysis model to predict the possibility and classification of tunnel leakage is established,eight main control factors of tunnel leakage are chosen in the analysis,such as,the depth of tunnel,the situation of vegetation covering of tunnel area,annual average rainfall of tu...
