摘要
针对重庆三峡地区易滑地层地质特性,充分收集和分析前人的研究资料及成果,运用通用颗粒离散元程序(UDEC)建立三峡库区顺层三级边坡模型,模拟过程中主要考虑层面倾角、碎落台宽度以及粘聚力等参数对边坡稳定性的影响,分析模拟计算得出的不同参数组合下的安全系数,提出易滑地层三级顺层边坡合理放坡坡形。
In the light of geological characteristics of easy slippery stratum on Chongqing three gorges area, existing literature and the results of previous studies were collected and analyzed sufficiently. Discrete elements soft ware, which is called UDEC was used to build models of bedding level 3 slope on three gorges area. The influence of sehistosity orientation, width of stage for heaping debris and cohesive force on the slope stability were mainly considered in the simulation. Safety factors with different parameter combination were obtained by analyzing the simulation, and on this basis we put forward reasonable Step-slope sloping of Level 3 bedding slope of easy slippery stratum.
