灌全高速公路某边坡变形机制及治理对策研究

Study on Deformation Mechanism and Countermeasures of A Slope along Guanquan Highway

通过对灌全高速公路K25+650^+890段顺层岩质边坡现场工程地质条件的系统调查,研究了该边坡的岩体结构类型及其成因机制、边坡的破坏机制及各组结构面的组合特征;在此基础上,通过三维仿真软件FLAC3D进行数值模拟,结合实际工程地质条件分析,进一步对该边坡的变形机制及变形过程进行分析,并预测其破坏形式。对该边坡重新进行了防护变更设计,取得了良好的结果。供类似工程参考。

Depending on systematic investigation of the engineering geological conditions of bedding rock slope alone K25 ＋ 650 - ＋ 890 Section of Guanquan Highway, this paper studied the type of rock structure thereof, the genetic and failure mechanism, and the features of each combination of structural planes, based on which numerical simulation was carried out with FLAC3D, a 3-dimensional simulation software, and combined with the actual geological conditions, to make a further analysis on the deformation mechanism and process of the slope and predict its failure mode, thus the slope protection design change was made and then got good result. For reference in similar projects.
