| Abstract: | According to crack and leakage problems of Shanghai subway stations, authors analyze the influence of temperature shrink stress of large volume concrete on cracking, and deduce such calculation formulas applicable for temperature shrink stress, crack separation and width of subway station structures. Authors also provide a technical method to solve the crack problem, and prove the feasibility of the method with calculation results of a practical example. |
