多倾角组合锚杆边坡支护模型试验

摘要

通过模型试验,对比分析单一倾角锚杆和多倾角组合锚杆对边坡的支护效果,并对多倾角组合锚杆边坡支护技术进行研究.研究结果可用于指导实际边坡工程中锚杆优化布置形式.%In order to compare the side slope support effect by uni-dip and multi-dip combined bolt, the model tests for uni-dip bolt and multi-dip combined bolt side slope support have been conducted respectively. The results have showed thatunder the action of uni-dip bolt, the deformation of slope is larger yet its ultimate bearing capacity is smaller, showing the characteristics of flexible failure;under the action of multi-dip bolt, the deformation of slope is smaller yet its ultimate bearing capacity is larger, showing the characteristics of fragile failure. The results may be used to instruct optimization arrangement of bolts in side slope support practice.
