| Abstract: | Aiming at the crack situation of an aqueduct of the water diversion project, we carry on the analysis from two running states of the flume, considering the error which is produced by the internal force calculation according to the old standard, uses a large-scale finite element analysis to analyze the running states, and analyzes the reason of the crack forming based on the using condition, and brings forward the reinforcement opinion and design suggestion about the similar flume. |

| Keywords: | flume crack temperature stress analysis model |
