摘要
为客观评价引水隧洞在运行期结构的健康状态,调查分析引水隧洞在运行期间影响其安全运行的各种病害问题,参考相关评价规范建立引水隧洞结构健康状态评价指标体系。运用投影寻踪(PP)原理构建引水隧洞结构健康状态评价模型,并用万有引力搜索算法(GSA)优化PP模型的最佳投影方向,得出各指标权重,进而得到评价投影值。以引大入秦工程盘道岭隧洞为研究对象对其结构健康状态进行评价,评价结果切合实际并与TOPSIS法评价结果基本相符。GSA-PP评价模型简单可操作,可运用于引水隧洞结构健康状态评价研究中。
In order to evaluate the health status of diversion tunnel structure during operation period, the problems of various diseases affecting the safe operation of diversion tunnel during operation were investigated and analyzed. The index system for evaluating the health status of diversion tunnel structure was established with reference to relevant evaluation norms. The projection pursuit(PP) principle was used to construct the health state evaluation model of the diversion tunnel structure. The optimal projection direction of the PP model was optimized by the universal gravitation search algorithm(GSA), and the weights of each index were obtained, and then the projection values were evaluated. Taking the Pandaoling tunnel as the research scope, the structural health status of the tunnel was evaluated. The evaluation results are in line with the reality and are basically consistent with the results of the TOPSIS method. The GSA-PP evaluation model is simple and feasible operation, and can be used in the study of structural health evaluation of diversion tunnel.
