Method for reinforcing deep-buried weak structural plane of rock slope
The invention discloses a method for reinforcing a deep-buried weak structural plane of a rock slope, and relates to the technical field of slope reinforcing engineering. The method comprises the following steps of excavating an adit with the axis coinciding with the trend of a fault along the fault of the slope; drilling anchor cable holes arranged in pairs from the left side wall and the right side wall of the horizontal section of the adit to the hanging wall rock mass and the footwall rock mass of the fault, enabling the axes of each pair of drilled holes to be on the same straight line, installing anchor cables in the holes, reserving steel strands with a certain length outside the anchor cable holes and arranging the steel strands in the adit; connecting the steel strands of the anchor cables on the two sides of the fault together through a special anchorage device and carrying out tensioning; and backfilling the adit with concrete to fill the whole section. The prestress is applied to the deep-buried fault in the slope to improve the stability of the slope, the difficulty that anchor cable reinforcement is difficult to conduct on the deep slip crack face is overcome, the method can also be combined with other forms of tunnels in the slope, the flexibility is good, and the reinforcement cost performance is high.
本发明公开了一种岩质边坡深埋软弱结构面的加固方法，涉及边坡加固工程技术领域，该方法包括：沿着边坡的断层开挖洞轴线与断层的走向重合的平洞；自上述平洞横断面的左、右两侧边墙分别向断层的上、下盘岩体中钻成对布置的锚索孔并使每对钻孔的轴线在同一直线上，在孔中安装锚索，并在锚索孔外预留一定长度的钢绞线置于洞内；通过专用锚具将断层两侧锚索的钢绞线连接在一起，并进行张拉；在平洞中回填混凝土，充填整个断面。发明通过在边坡内部对深埋断层施加预应力以提高其稳定性，克服了深部滑裂面难以进行锚索加固的困难，还可与边坡内其他形式的隧洞相结合，灵活性好，加固性价比高。
