山区覆土罐施工开挖过程中将产生多个边坡,开挖坡比大小影响施工安全和工程造价。利用Zsoil有限元软件,建立覆土罐边坡开挖的地质模型,对覆土罐边坡开挖的稳定性进行评价,结合工程实例分析,给出覆土罐边坡开挖的最优坡比建议。 A number of slopes will be generated during the excavation process of the soil-covered tanks in the mountainous area, and the size of the excavation slope will affect the construction safety and the project cost. Zsoil FEM software was used to establish a geological model of the excavation of the overburden tank slope. The stability of the slope excavation of the overburdened tank was evaluated. Combined with the engineering example analysis, the optimal slope ratio of the excavation of the overlying soil tank was proposed.
