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；
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.
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。
