失稳

The results indicate that the μ of the asphalt mixtures has significant effect on the maximal lateral and shear strains. When the modulus ratio of the top and middle lagers is less than 0.8 and the μ of the asphalt top layer increases to a certain extent, the asphalt mixtures around the edge of wheel mark tend to flow towards both sides of the rut under the action of load, leading to the unstable rut.

结果表明，沥青面层的泊松比对沥青路面结构的最大横向应变和最大剪应变有显著影响：当上中面层模量比小于0.8且沥青面层泊松比增大到一定程度时，轮迹带边缘的沥青混合料在荷载作用下有向车辙两侧流动的趋势，容易产生失稳性车辙。

The results showed compared with the native state the shear strength of rockmass under the saturation state decreased by 11.17%, cohesion force decreased by 16.09%, internal frictional angle decreased by 10.02%.(3) 3D-σFEM numerical simulation software is used to simulate the slope stability on the native state and saturation state. Compared with the nature state the displacement of the discontinuity and stress concentration in the saturation state is largened clearly, the results showed slope stability under the rainfall is weakened.

更多含有天然结构面的岩体试件进行了不同含水量下的强度试验，试验结果证明在岩体试件处于饱水状态时的结构面抗剪强度比天然状态下平均下降了11.17%、粘聚力平均下降了16.09%、内摩擦角平均下降了10.02%；(3)采用3D-σ有限元数值软件对K86+180～K86+470段岩质边坡进行了三维有限元数值模拟，并且分天然状态分阶段开挖和饱水状态分阶段开挖两种不同状况进行了稳定性分析，从分析结果可以看出与天然状态相比，饱水状态下软弱层水平方向位移明显增大，坡脚及软弱层特别是软弱层临空面附近的剪应力值显著增大，并且其安全系数与天然状态相比也显著减小，说明在有大的降雨发生当岩体处于饱水状态时边坡整体稳定性被削弱，边坡失稳可能性增大。
