【摘要】 以某路堑边坡为例,建立数值模型计算了路堑开挖过程对变形稳定性的影响情况,计算结果显示,坡体内软弱夹层对边坡的稳定性影响较大,应提高重视,边坡在该夹层处出现了较大的水平位移,因此该夹层是潜在的滑移面,在开挖坑底出现了较大的隆起现象,也应提高重视,避免道路修筑以后出现开裂现象。更多还原

【Abstract】 A cutting slope was taken as an example,and a numerical model was established to calculate the stability of the slop under excavation process.The calculation results show that the weak intercalation of a slope affects slope stability terribly,there is large level displacement in the mezzanine,and the mezzanine is a potential slip surface.There was greater uplift in the pit bottom under excavation.In order to avoid cracking phenomenon of road construction,attention should be also improved.更多还原
