【摘要】 许多膨胀土边坡在长期的地质和干湿循环的自然气候作用下裂隙逐渐发展,以致被裂隙分割成块体系统。将膨胀土边坡看成是一个具有非饱和土本构关系、块体间存在摩擦力和膨胀力和具有牵引式滑动及时空效应特点的块体系统,建立了一种新的边坡稳定性非连续变形分析方法,并应用于某高速公路段膨胀土边坡稳定性的分析中,获到了很好的效果。更多还原

【Abstract】 Affected by geology and natural weather of dry and wet cycles,many slopes of expansive soil lead to the development of the fissures and finally became a block system. To take the slope of expansive soil as a block system in which soil blocks have constitutive relation of non-saturated soil,there are frictional and expansive forces between the blocks,and there is a feature of towed slide and effect of time and space. A new method of discontinues deformation analysis are formed for the slope stability analysis of the expansive soil. This method is used to analyze the stability analysis of some slopes of the expansive soil in a highway,and very good results are available.更多还原
