Abstract
There are three faults in the inlet slope of the tunnel-spillway of Shuangjiangkou Hydropower Station,which cut each other to form a typical"steep-gentle"combined slip mode,which seriously affects the layout of the spillway inlet.Based on the characteristics and layout conditions of spillway,the author analyzes the defects of guide wall shape and pier design,and explores reasonable reinforcement of sluice chamber.The results show that the elliptical straight wall guide wall has more advantages in the design of ultra-short guide wall with a length of no more than 15 m;Combined with the calculation of eccentric compression members and the finite element calculation results of the joint continuum model of pier and bedrock,it is more economical and reasonable to determine the reinforcement of pier;When calculating the reinforcement of the fan-shaped steel bars in the pier,the thrust is 0.2 times of the thrust of the working arc gate with reference to similar engineering experience,but the rationality of the value needs to be further verified.The research results can be used as reference for similar projects.关键词
