不同种类边坡与锚索抗滑桩间接触应力分布规律的探讨

Discussion on the Distribution Rule of Contact Stress Between Anchor Anti-slide Piles and Different Types of Slopes

为研究不同种类边坡与锚索抗滑桩间接触应力的分布规律,首先介绍FLAC3D中接触面的基本理论,然后通过三个算例初步说明不同边坡情况下接触应力的分布规律,最后运用正交分析方法量化分析接触面参数对接触应力影响的显著性。研究结果表明:数值模拟结果与实际情况吻合良好,为实际工程实施提供理论依据。

In order to study the distribution rule of contact stress between anchor anti-slide piles and different types of slopes,the basic theory was introduced in FLAC3 D firstly,and then,the distribution of contact stress under the condition of different slopes was illustrated through three examples. In addition,the significant influence of contact stress on interface parameters was analyzed quantitatively by using the orthogonal analysis method. The results indicate that numerical simulation results are in agreement with the actual situation,which will provide a theoretical basis for the implementation of the actual project.
