| 摘 要： | 在衬砌独立工作的前提下,提出一种透水衬砌裂缝宽度计算的简单方法。实例计算表明:若允许衬砌裂穿,裂缝在稳定渗流状态下的长期稳定开度较小,按透水衬砌限裂设计,可大量节省钢材,方便施工。

| Abstract: | A simple method for calculating the width of cracks in previous permeable concrete lining is presented,with the premise of independent work of the lining.The example shows that if crack penetration is allowed,the long-term stable crack opening is smaller in the steady seepage state.It also shows that,according to the crack width limit of the permeable lining,this method can save a lot of steel and is easy to construct. |
