层状页岩边坡群锚加固效应的模型试验探索

Analysis on the group anchor reinforcing effects in the bedded shale slope through model tests

本文以一实际公路边坡为原型,利用模型试验的相似原理,对川南层状页岩边坡采用室内模型试验的方法对边坡群锚加固处理中最佳锚固间距、锚入角度、变形和破坏情况以及页岩边坡本身的层状节理对群锚效应的影响等进行了初步探究,得出了对层状节理页岩边坡进行群锚加固时有关强度与位移的初步规律,并将试验结果应用到了该路段后续工程的处理当中,效果良好,为工程界进一步探索群锚效应提供参考。

Based on an actual road slope and the similarity principle of model testing, the best distances between anchors, the anchor angle, the deformation and failure and the influence of the layer shale on the multi-bolts anchoring effect are studied for the layer shale in South Sichuan province, and the primary rules for the multi-bohs anchoring in the layered joint shale are discussed. The final testing results are used in the following construction of the road section, which provide the references for the further study on the multi-bolts anchoring effect.
