| 摘 要： | 采用离散元数值模拟软件UDEC2D4.0对山体下部岩层的原岩应力场分布规律进行研究。根据山体下部岩层受山体影响强度的不同分为3个区,即距地表100 m以内的明显影响区、距地表100~250 m的影响减弱区和距地表250 m以下的无影响区,同时得出在山峰内部存在应力降低区,在山谷内部存在应力增高区。

| Abstract: | Using discrete element simulation software UDEC2D4.0 to research the distribution law of the situ stress field in rock under mountain. Studies suggest that rock stratum under mountains can be divided into three area, significantly effect area distance to surface less than 100 m, effect decreased area distance to surface 100~150 m and no effect area distance to surface more than 250 m, and the peak internal stress decreasing zone, the valley internal stress increasing zone. |
