| 摘 要： | 通过对粤北山区龙怀高速公路K153（翁源段）路堑滑坡成因分析，得出滑坡是基于路堑开挖、水库水位补给、滑带土高液限性、岩层顺倾等因素诱发古滑坡局部复活的结论。运用GEO-Studio边坡稳定性模块SLOPE/W极限平衡法进行稳定性计算，并采用锚索框架梁辅以排水措施治理滑坡，通过2个雨季的考验，证明该治理措施可行有效。

Genesis Analysis and Treatment Measures of Cutting Landslide along Wengyuan Section of Longchuan-Huaiji Highway |
| |
| Abstract: | Depending on the genesis analysis of the cutting landslide along K153(Wengyuan)Section of Longchuan-Huaiji Highway in the mountainous area of northern Guangdong, it was found out that the landslide was resulted from local revival of ancient landslide and induced by the factors, such as cutting excavation, reservoir water supply, high liquid limit of sliding soil and downdip rock stratum, and then with the SLOPE/W slope stability module in GEO-Studio, its stability was calculated by limit equilibrium method. It was controled by anchor frame beam together with drainage measures. After experiencing two rainy seasons, these control measures were proved to be feasible and effective. |
