Heat Damage of High-Temperature Rock Tunnel by Weighted Residual Method in Tibet Plateau

Abstract:

According to the weighted residual method to deduce the finite element method of temperature field. The Jiwoxiga high-temperature rock tunnel on the Lhasa-Shigatse railway line is taked for example in the paper, then the actual drilling temperature data was combined to establish three-dimensional finite element model, the basic characteristics of temperature field was forecasted, the basic rule of temperature was obtained and the data can be compared with the actual data. It can provide references for the actual construction and ensure the similar engineering construction.
