Abstract:
The inlet slope of Spillway tunnel at a hydropower station is reinforced with the prestressed anchor cable. The reasonable selection of anchor parameters affects the reliability and economy of engineering reinforcement directly. In this paper, sensitivity analysis was performed on four anchor parameters (anchor angle Φ, anchoring force T, anchor spacing H, and anchor cable length L ) of the anchor slope, and the finite element method was used for parameter optimization design based on the results of sensitivity analysis to obtain the best anchor parameters for reinforcement of prestressed anchor cable. The results can offer valuable references to improve the reinforcement effects of excavation slope and reduce the cost of project design and construction.
