广河高速公路滑坡原因分析及综合治理

以广河高速公路K66+250~+580滑坡地勘资料为基础，结合现场调查，对滑坡地质环境、滑动过程、滑动原因及稳定性进行综合分析。通过现场地貌形态的特征、滑坡变形形态、监测数据、结构面的配套等分析，推断出滑坡的滑动面，计算出滑坡典型断面剩余下滑力，并以此为依据对滑坡进行桩锚结合的综合治理，通过监测对滑坡病害分析及综合治理进行验证，治理效果较好。

Genesis Analysis and Comprehensive Treatment of Landslide along Guangzhou-Heyuan Highway

Based on the geological survey data of the K66+250~+580 Landslide along Guangzhou-Heyuan Highway, this paper, by combining with the field survey, analyzed the geological environment of the landslide, the sliding process and genesis, and the stability thereof. Through the analysis of the landform features in the field, the landslide deformation form, the monitoring data and structural plane, the sliding surface of the landslide was deducted and the surplus sliding force on the typical section of the landslide was calculated; then depending on this, the comprehensive treatment of pile-anchor combination against the landslide was carried out. Finally through validation of landslide disease analysis and comprehensive treatment by monitoring, it was found that the treatment effect is good.
