摘要

为了准确分析土石混合边坡的稳定性，克服传统有限元和颗粒流程序在分析土石混合边坡稳定性上的不足，提出一种基于原始土石混合边坡的图像识别和块石随机生成技术，运用此技术生成土石混合边坡模型

模型中较大块石的尺寸范围为0.1~0.3倍坡高，并采用强度折减法对5种不同较大块石分布位置的土石混合边坡的稳定性进行了分析研究。结果表明：不同的较大块石分布位置对土石混合边坡稳定性的影响较大，影响的大小关系为：坡脚>坡面>坡顶>坡内>坡后>均质土坡；在同一较大块石分布类型下，不同的块石随机位置及排列方式对土石混合边坡的塑性扩展模式有着较大影响。研究结果可为土石混合边坡的设计及施工提供参考依据。

Abstract

In order to accurately analyze the stability of soil-rock mixed slopes and overcome the shortcomings of the traditional finite element and particle-flow software in analyzing the stability of soil-rock mixed slopes

a method based on image recognition of original soil-rock mixed slopes and generation of random rocks

was put forward and used to generate slopes with random rock distributions. The size range of the larger rocks in the model is 0.1 to 0.3 times of slope height. The strength reduction method was used to analyze the stability of soil-rock mixed slopes according to five kinds of rock distributions. The results show that the distribution of larger rocks in soil-rock mixed slopes have larger influence on the stability of slope. The main influential factors follow the sequence of slope toe

slope surface

slope crest

inside slope

behind slope and on uniform soil slope

based on the distribution of larger rocks. The random location and arrangement of rocks have great influence on the plastic zone propagation mode of soil-rock mixed slopes under the same rock distribution type. This research can provide reference for the design and construction of soil-rock mixed slopes.
