| 摘 要： | 对黄延高速公路黄土边坡坡面剥落进行了稳定性评价.假定边坡剥落面为平面且平行于坡面,各点应力状态相同,不考虑坡端阻力的影响,根据极限平衡理论,建立剥落体稳定性分析模型.采用该模型对黄延公路黄土边坡剥落病害进行分析,结果表明,黄延高速公路的路堑边坡易在Q3e01黄土层中发生剥落,评价结果与调查结果相符合. |

| Abstract: | Based on Huangyan expressway,spalling stability of loess slope has been evaluated.Assuming the spalling surface be parallel to the slope surface,every point stress station be same,without considering the effect of end-resistance,the stability analysis model of spalling mass is built based on the Limit Equilibrium theory.This model is used in the loess slope spalling mass stability analysis in Huangyan expressway.The result shows that the spalling occur more often in Q3eol loess layer.The result meets well w... |
