| 中文摘要:已变形的碎裂结构临时边坡如不及时治理，极可能出现边坡失稳，而碎裂结构边坡对支护措施适应性差，并且临时边坡抢险治理工程中更要权衡经济因素，所以此类边坡治理难度较大。以大渡河某已变形碎裂结构临时边坡为例，根据碎裂结构临时边坡的特点对边坡治理结构进行了选型，分析了边坡施工顺序对边坡抢险治理工程的影响。采用第一时间进行坡体位移监测，并通过监测孔施工反馈信息及时调整治理方案，使用挂网喷混、锚索配合横梁、钢筋桩和排水工程对碎裂结构临时边坡进行了抢险治理。通过数值模拟和监测数据进行了验证，结果表明治理方案经济、适用。 |

| Abstract:Slope failure very likely occur if the deformed temporary slopes with cataclastic structure were not treated immediately, but cataclastic slope requested exigent support and the cost was also an important factor in the enginneering, these increased the treatment difficulties. The paper took the case of a cataclastic temporary slope on Dadu River, based on the characteristic of cataclastic temporary slope, treatment model was selected and the effects of working sequence of slope treatment were analyzed. Displacement monitoring in slope was made in first time and according to the feedback information, treatment scheme was adjusted with wire-netting shotcrete, prestressed anchorage cable, reinforcing steel bar piles and drainage engineering. Verification by numerical calculating and monitor data showed the treatment scheme was economy and applicable. |
