摘要
红土中加入玻璃纤维,其界面作用特性将发生变化。试验结果表明,压实度、含水率、剪切速率、玻璃纤维的特性、干湿状态等因素都会影响玻璃纤维与红土的界面作用能力,总体表现为界面抗剪强度低于红土本身的抗剪强度,其界面作用特性可用界面剪应力因数、界面粘聚力因数和界面摩擦因数来衡量,其界面作用机理可用粘结嵌固作用和隔离作用来解释。
The interaction characteristics will vary when laterite is mixed with fiberglass. The direct shear test demonstrate that the factors, such as the compaction and water content of laterite, the shear rate of the test, and the properties and wetting and drying status of the fiberglass, will impact the interactions in which the interface will resist lower shear than the laterite itself. The properties of the interaction can be estimated by shear stress factor, cohesion factor and friction factor at the interface in which the functions can be described by wedge, viscidity and isolation.
