Simulation Analysis of Temperature and Stress of Rock-anchored Beam during Construction

Rock-anchored beam is a common structural form in underground plants of modern large hydropower stations. Due to the long length of the construction section of the rock-anchored beam, the high concrete grade and a large amount of pouring, temperature control and crack prevention are relatively difficult. This paper analyzes the feasibility of water cooling to improve the crack resistance of rock-anchored beam concrete, and puts forward the corresponding measures of temperature control and crack prevention for reference of similar projects.
