基于强度折减法的抗滑桩桩位优化设计研究

The Research on the Optimization Design of Anti-slide Pile Position Based on the Strength Reduction Method

抗滑桩设计中桩位是决定设计成败的一个重要影响因素。结合某高速公路滑坡处治实例,基于强度折减法对不同桩位下滑坡的加固效果进行数值模拟。结果表明不同桩位对滑坡体稳定性的影响较大,当抗滑桩布设于滑体阻滑段中部时能起到较好的加固效果。结论为抗滑桩的优化设计提供了依据,对此类工程有一定的借鉴意义。

Combined with the example of a highway landslide treatment, this paper had the numerical simulation of the landslide reinforcement effect under the different pile position based on the strength reduction method. The results showed that the different pile position had great influence on the stability of landslide body.When the anti-slide pile was set in the middle of the sliding block section, the reinforcement effect could be better. The conclusion provided the basis for the optimization design of anti-slide, which had certain reference significance for this kind of engineering.
