| 摘 要： | 提出了一种在巷道两帮打入水平锚杆用以防止软岩巷道底鼓现象的方法。在分析巷道底鼓产生原因的基础上, 结合抗滑桩绕流阻力理论, 从理论上确定了锚杆支护参数。在不考虑围岩内粘聚力的情况下, 对水平锚杆和底角锚杆防治软岩巷道底鼓的参数、施工工艺进行了对比, 列举了各自的优点与不足。

| Abstract: | Aiming at the floor heave in the soft-rock tunnel, it was proposed to set horizontal anchors on both sides of roadway. Based on the analysis of floor-heaving reason, anchor supporting parameters were determined with the theory of circle resistance of anti-slide pile. Without the internal cohesion taken into account, the supporting method by horizontal anchor was compared with that by ground anchor in terms of parameters and construction techniques. The pros and cons of each method were all listed. |
