汤河水库溢洪道在1978年加固后,在运行过程中闸墩出现多条裂缝,基底出现严重漏水现象,通过稳定和应力分析计算,确定为在某些特殊荷载组合情况下基底出现拉应力所致,证明了汤河水库溢洪道运行存在重大安全隐患,对把握工程运行和进行工程加固提供了有力的科学依据。
After the reinforcement of the Yuhe reservoir spillway in 1978, several cracks occurred in the pier during operation, and the basement suffered serious water leakage. Through the calculation of stability and stress analysis, it was confirmed that the tensile stress of the basement occurred under some special load combinations It proves that there is a major safety hazard in the operation of the spillway of Tanghe Reservoir and provides a strong scientific basis for grasping the operation of the project and strengthening the project.
