通过对平煤集团大量的锚喷巷道的回归分析，建立了巷道壁面绝对粗糙度和巷道断面积对摩擦阻力系数影响程度的回归方程，并对回归方程作了显著性检验，最后对巷道粗糙程度和断面积对锚喷巷道摩擦阻力系数的影响程度进行了讨论和总结，对同类巷道摩擦阻力系数的选取具有实践指导意义。 - Based on the pull - out tests data between geogrids and expansive soil / sands arranged by the orthogonal table l9 ( 34 ) , the following conclusions are reached : 1 ) the displacement - properties of pullout tests depend on the pullout speed . the law of factors " affecting degree , which influences the parameters between geogrids and soils in the pulling - out procedure , is obtained . with the concept of " equivalent pull - out displacement ( x ) " brought forward , the whole process of pull out tests is divided into two process - " main process ( when x 1 . 0 ) " and " residual process ( when x 1 . 0 ) " , and three stages - static friction resistance stage , slip friction resistance stage , and residual friction resistance stage
基于正交设计表l9 ( 3 ~ 4 )分别安排了影响因素与土工格栅膨胀土或砂土界面相互作用参数的拉拔试验数据，获悉： 1 )拉拔试验位移特性主要取决于影响因素中拉拔速率；通过分析并获取影响因素对筋土界面相互作用参数的影响程度及其在拉拔试验过程中的变化规律，提出了当量拉拔位移( x )的概念，并据此将拉拔试验全过程划分成“主过程( x 1 . 0 ) ”和“残余过程( x 1 . 0 ) ” ；且将影响因素对拉拔力或摩擦阻力系数的影响程度分成三阶段(静摩擦阻力阶段、滑动摩擦阻力阶段，残余摩擦阻力阶段) ； 2 )不同(规范)定义的筋土界面摩擦阻力系数数值相差较大，但影响因素对摩擦阻力系数影响程度及其变化规律不会因不同(规范)定义而受到影响。
