摘要
为确保滑坡区内居民的生命财产安全,基于滑坡的地质条件,利用传递系数法等方法对滑坡稳定性进行研究,并筛选合适的滑坡防治方案;通过支持向量机实现滑坡防治后的变形预测,并以预测结果评价滑坡防治效果。结果表明:1)滑坡稳定性的定性评价结果与定量评价结果具有较好的一致性,综合评估得出,滑坡稳定性总体处于不稳定-基本稳定,尤其是在暴雨工况条件下,滑坡失稳风险较大;2)经滑坡防治方案的筛选,得出方案1“抗滑桩+排水”的适用性相对最佳,其适用性等级为4级,优于其他两类防治方案;3)通过对滑坡防治实施后抗滑桩的变形监测成果分析可知,抗滑桩的变形已趋于收敛,最终预测值范围为24.45~27.82 mm,始终在变形控制限值范围内,充分说明滑坡防治措施合理且有效,达到了预期的防治目的。
In order to ensure the safety of life and property of residents in the landslide area,based on the geological conditions of the landslide,the stability of the landslide is studied by using the transfer coefficient method and other methods,and the appropriate landslide prevention and control schemesare screened.The support vector machine is used to predict the defornation after landslide prevention,and the prediction results are used to evaluate the landslide prevention and control effect.The results show that:1)The qualitative evaluation results of landslide stability have good consistency with the quantitative evaluation results.Comprehensive evaluation shows that the stability of landslides is generally unstable-basically stable,especially under heavy rain conditions,where the risk of landslide instability is high;2)After the screening of landslide prevention and control schemes,it is concluded that scheme 1"anti-slide pile+drainage"has the best applicability,and its applicability level is level 4,which is better than the other two types of prevention and control schemes;3)Through the analysis of the deformation monitoring results of the anti-slide pile after the implementation of landslide prevention and control,it can be seen that the deformation of the anti-slide pile has tended to converge,and the final predicted value range is 24.45~27.82 mm,which is always within the range of deformation control limit,which fully shows that the landslide prevention and control measures are reasonable and effective,and the expected prevention and control purpose has been achieved.
