工程实践证明采用锚管注浆加固弱面岩质边坡是一种十分有效的方法.在注浆过程中,注浆锚管的堵赛长度是一个非常重要的参数,它受到钻孔直径、锚管直径、注浆压强等多种因素影响.通过先求解注浆过程中浆体与锚管、浆体与边坡岩体之间的力学形态,得出其判断方程,然后再运用正交试验得出影响锚管堵塞长度的因素.最终得出钻孔直径和注浆压强对锚管堵塞长度的影响最大,并求出锚管堵塞长度的最小值和最大值,确定了其堵塞长度的合理范围,对工程施工有一定的指导意义.
Engineering practice proves that it is a very effective method to reinforce weak-face rock slope by grouting with anchor pipe.In the process of grouting, the blocking length of grouting anchor pipe is a very important parameter, which is affected by the diameter of the borehole, The diameter of anchor pipe, the pressure of grouting and so on.Through solving the mechanics between slurry and anchor pipe, slurry and slope rock mass in the process of grouting, the judgment equation is obtained, then the orthogonal The factors that affect the length of blockage of the anchor pipe are obtained.Finally, it is concluded that the influence of the hole diameter and the grouting pressure on the blockage length of the anchor pipe is the greatest, and the minimum and maximum length of the blockage of the anchor pipe are obtained. Reasonable range of construction has a certain significance.
