摘要
兰州金城公园石头坪景区提升改造工程存在大量的自然边坡和人工边坡。因边坡土体物理力学参数存在变异性,采用了蒙特卡洛随机抽样法和极限平衡法按不同坡高及坡度计算分析了边坡稳定可靠性指标及其变化规律,结果表明在景区实际坡高、坡度范围内边坡是稳定可靠的,适宜景区建设,但当坡高、坡度达到实际范围的最大值或超范围时,边坡处于基本稳定或欠稳定状态,建议采取加固措施。
There arc a large number of natural slopes and artificial slopes in the upgrading project of the Shitouping scenic area in Jinchcng Park of I.anzhou. Duc to the variability of the physico mechanical parameters of slope soils, the Monte Carlo random sampling method and limit equilibrium method wcrc used to calculate and analyze the slope stability reliability indexes and the change rules according to different slope heights and gradients. The results show that the slope is stable and reliable in the area of the actual slope height and slope gradient range, which is suitable for the scenic spots construction. However, when the slope height and slope gradient reach the maximum or over-rangc of the actual range, the slope is in a basically stable or under-stablc state, the reinforcement measures arc suggested.
