摘要
为了研究岩质高边坡支护结构体系的加固效果,结合石家庄至武汉铁路客运专线DK1126-997.09～DK1127-085.27岩质高边坡工程实例,利用ANSYS有限元软件数值模拟对其进行稳定性分析。对各种支护方案在开挖后岩质高边坡应力场、位移场分布以及抗滑桩应力进行比较分析,结果表明:边坡开挖后,框架梁锚杆(索)支护显著地减小了边坡的水平位移,改进了应力场的分布以及减小了抗滑桩的应力峰值,有效地增强了岩质高边坡的稳定性。
In order to study the reinforcement effect of supporting structure system of high rock slope,combined with a real project in Shijiazhuang-Wuhan high-speed railway, the effect can be analyzed through numerical simulation method. This paper compares and analyzes the stress of pile, displacement and stress distribution of excavated high rock slope. Numerical simulation results show that the frame supporting structure with rock-bolts is significantly helpful for the improvement of surface layer of the slope in the terms of displacement and stress distribution so that the stress value of pile is reduced . Therefore, the frame supporting structure with rock-bolts is more effective to enhance the stability of high rock slope.
