摘要
为找到渠道刚性衬砌层最优断面,作者从理论上进行了受力分析。结果表明:圆弧底U应为理论最佳断面;并在不同的地下水埋深情况下,给出了计算公式。而且在实践中证明了其正确性。
In order to find out the superior section of the rigid channel liner layer,the analysis of press from the theories was made. The result showed：the arc bottom U should be the best section in theories ;under different groundwater deepness,the calculation formula was given. And its accuracy was proved in fact.
