We can get the result that the control work condition of surge shaft is maximum surge water level, and the distribution of stress is accord with standard because most values remain within the limits of allowable tensile stress. 得出最高涌浪水位是调压井的控制工况,调压井结构的应力分布符合常规,其值大部分在混凝土的容许拉应力以内,局部出现大应力区,需要加强配筋;
There will be a certain thermal stress in the lining during operation, but the stress is not great, being only about one tenth of the allowable tensile stress of the reinforcing bars. 4,隧洞衬砌运行时具有一定的温度应力,但其值不大,仅为钢筋允许拉应力的十分之一左右。
The new formula for computing the allowable tensile stress given in the new specifications is not reasonable. 该规范提出了一个混凝土允许拉应力计算公式,这个公式不宜采用;
