ABSTRACT
Cracks are often found at lining concrete of flood discharging tunnel during construction. Previous studies have shown that temperature stress is the main cause leading to cracks during construction. The cooling pipes method is one of the important measures to control temperature. The equivalent heat conduction Finite Element Method (FEM), because of its simple, is usually applied to simualte the temperature field. The FEM with cooling pipes which can simulate the temperature field accurately has rarely been reported. For this reason, the lining concrete of Xiluodu underground engineering flood discharging tunnel Longluowei section is simulated by FEM with cooling pipes. Good simulated results are obtained comparing with the experimental data and some very useful conclusions can be applied for site analysis to prevent cracks.
