摘要
反倾层状岩质边坡灾变过程隐蔽,变形破坏机理复杂,边坡一旦失稳,往往造成严重的灾难性后果。青岛市经济开发区扒山边坡为典型的反倾层状岩质边坡,选取以锚杆+墙为主要支护方法。由理论推导和UDEC数值模拟确定合理支护参数和合理注浆压力,并对该方案的支护效果进行模拟评估。
The disaster process of anti-dip sandwich rock slope is hidden, and the mechanism of deformation is complex. Once the slope is unstable, it often causes serious disastrous consequences. Pashan mountain slope of Qingdao economic development zone is typical of the anti-dip sandwich rock slope. The anchor rod retaining wall was chosen as the main supporting method. The reasonable supporting parameters and the reasonable grouting pressure are determined by the theoretical deduction and the UDEC numerical simulation, and overall stability of the slope is analyzed by numerical simulation.
