摘要
猴子岩库区复建公路部分明线路基边坡出现三级拉裂缝,影响路基稳定。为查明滑坡的形成机制、滑坡规模,为治理滑坡提供资料,在前期地质勘察的基础上进行了补充地质勘探,查明了滑坡体覆盖层厚度及滑移面形态,并对其稳定性进行了评价。评价结果表明,在天然条件下,滑坡体处于欠稳定状态,局部处于欠稳定-不稳定状态,需进行治理。经研究,提出了采用框架+锚索(锚杆)加固的优化治理方案。
Grade III tensile cracks appeared on partial landslide slope of road rehabilitation project in Houziyan Reservoir Are-a, influencing the stability of road bed. To identify the formation mechanism and scale of the landslide for its subsequent harness-ing, the geologic probe was supplemented on the basis of preliminary geologic examination. The landslide coverage and sliding plane patterns were identified, and its stability was evaluated. It is indicated that the landslide is in a state of slightly instability generally, with local instability under natural conditions, worthy of being harnessed. In addition, the paper presents an optimiza-tion harnessing scheme with anchorage cable ( anchor rod) frame.
