Scope

Main technical content: 1.0.1 This guideline is formulated to standardize the design principles and technical requirements of reinforced concrete-lined water conveyance tunnels in pumped storage power stations. 1.0.2 This guideline applies to the design of reinforced concrete-lined water conveyance tunnels in pumped storage power stations. 1.0.3 For reinforced concrete-lined water conveyance tunnels with internal water pressure exceeding 200 m water head, special studies on ground stress, hydraulic splitting, and high-pressure water injection should be conducted on the surrounding rock. 1.0.4 For reinforced concrete-lined water conveyance tunnels with internal water pressure exceeding 200 m water head, seepage field analysis and analysis of the permeability stability of the surrounding rock and treatment measures should be conducted. 1.0.5 In addition to complying with this guideline, the design of reinforced concrete-lined water conveyance tunnels in pumped storage power stations shall also comply with the provisions of the relevant national standards currently in force.
