ANALYSIS OF TEMPERATURE DISTRIBUTION AND THERMAL STRESS OF YANGTZE RIVER TUNNEL LINING SUBJECTED TO FIRE LOAD

摘要：

Based on the Wuhan Yangtze River tunnel of major construction project，Three different kinds of fire-loading on the shield of tunnel are simulated and analyzed by using the simulation technology. Displacement temperature field and the thermal stress of bottom，top and lateral in a shield tunnel are calculated with different fire load. The rule of the temperature field distribution of shield tunnel lining by fire loading is studied. The most vulnerable section in shield tunnel is found. All could give a reference to fire-resistance design of shield tunnel.
