中文摘要：

以武隆鸡尾山滑坡滑体灰岩为研究对象,基于室内常规岩石力学试验,探讨了饱水与风干岩样的物理力学特性及其对高边坡稳定的影响机制,研究了灰岩渐进破坏过程中裂纹应变随加载的变化情况。试验结果表明,与风干试样相比,饱水试样的峰值强度和弹性模量较低,而泊松比较高,表现出较强的软化性;试样的裂纹起裂应力较低,而裂纹破坏应力较高。研究表明在岩质高边坡稳定性早期识别分析时,计算参数和稳定性判据的选取尤为关键,应引起足够的重视。

英文摘要：

Based on conventional laboratory rock experiment of the limestone of Ji Weishan landslide mass in Wulong County,the physical and mechanical properties of saturated and dried rock samples are discussed as well as its impact on stability of high rock slopes,and the crack strain is also studied increasing with loading during the progressive failure. The results show that,compared with the dried sample,the peak strength and elastic modulus of the saturated sample are lower,the passion＇s ratio is higher,the saturated sample show strong softening; the crack initiation stresses under two conditions are relatively low,while crack damage stresses are higher. Studies show that,during the early identification of high rock slope stability,the selection of calculation parameters and stability criterion are particularly critical and should be taken seriously enough.
