温度场反分析法确定大坝渗漏通道位置
Detection of the Dam Leakage Passage Position Based on Reverse Analysis Method of Temperature Field
摘要
Abstract
When an embankment has a concentrated leakage passage,the heat exchange with groundwater and rock media will occur around leakage passage,and this leads temperature altering in the stratum near leakage passage. Temperature tracer method is a universal method using tempera-ture field to research the dam leakage,but it’s almost the qualitative analysis at present. Only by determining the exact location and size of leakage passage,can the leakage problem be effectively controlled. In this paper,the Matlab optimization program was written based on the model for de-tecting multiple concentrated leakage passages. By optimizing and fitting leakage passage lines of the specific engineering,we calculated the leakage position quantitatively. Compared with analysis results of the measured temperature of drill holes,the results were the same. As a result,it is feasi-ble to use the method to detect the exact location of leakage passage.关键词
