| 摘 要： | 保证安全性和经济性是料场开挖的主要目标.基于这两个目标,以有限元软件ANSYS建立料场边坡的三维网格模型,在综合考虑现场地质条件、位移、应力、塑性区、安全系数和开挖方量等影响因素基础上,采用有限差分程序FLAC3D对开挖边坡的整体稳定性进行计算;并对考虑不同开挖高程和开挖坡比的4种开挖方案进行对比分析,为工程施工提供优选方案.研究表明:在优选方案下,开挖边坡稳定性能够得到保证,弧形马道的圈顶部分应该采取加固措施.

| Abstract: | To ensure stability and economy is the main objective of the excavation.Based on these two objectives,a three-dimensional model is established for a yard slope using ANSYS.Considering the in-situ geological conditions,displacement,stress,plastic zone,safety factor,volume of excavation,etc.,the overall stability of excavated slope is calculated by using FLAC 3D.And four schemes of different elevations and different gradients are analyzed in order to provide optimization scheme.It is shown that: in the optimi... |
