摘要
在混凝土护面板上开孔,一方面可增大与坡面的摩阻力,提高抗滑性能;另一方面增大了护面层的渗透系数,增强了面板的整体稳定性。通过不规则波系列试验,对不同开孔率混凝土护面板稳定性的影响因素进行了研究,提出了稳定厚度计算公式,并与现行规范的混凝土板和栅栏板稳定厚度公式进行了对比。该公式具有较好精度,可为工程设计提供参考依据。
Perforating on armoring concrete slabs can increase the permeating coefficient of the armoring layer, reduce the uplift forces and enhance the overall stability. A series of experimental tests on irregular waves are carried out to analyze the influential factors on the value of the relative net uplift forces of the armoring concrete slabs with different porosities. The calculation formula of the maximum relative net uplift forces is deduced, which is then compared with the previous formula.
