摘要
为了研究复合土工膜与砂浆的摩擦特性,通过不同的复合土工膜与砂浆组合进行室内直剪摩擦试验,得到复合土工膜与砂浆的摩擦系数以及摩擦特性规律。研究结果表明:二布一膜和砂浆的摩擦系数稍大于一布一膜和砂浆的摩擦系数;复合土工膜与砂浆界面的摩擦过程在不同阶段基本上为粘聚力和滑动摩擦力在发挥作用;复合土工膜和砂浆的破坏形态为脆性破坏。
Composite geomembrane is widely used as an impermeable material in engineering.Its interface friction with mortar directly determines the anti-sliding stability of the building.In order to study the friction characteristics of composite geomembrane and mortar,the indoor direct shear friction test is carried out by different composite geomembrane and mortar,and the friction coefficient and law of friction characteristics of composite geomembrane and mortar are obtained.The results show that the friction coefficient of the two fabrics and mortar is slightly larger than that of the one cloth and the mortar;the friction process of the composite geomembrane and mortar interface is basically the cohesion and sliding friction at different stages.The failure mode of composite geomembrane and mortar is brittle failure.
