摘要
结合石家庄至武汉铁路客运专线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,减小了抗滑桩的水平位移,有效地增强了岩质高边坡的稳定性。
Taking the project of high rock side slope support on the special passenger train railway from Shijiazhuang to Wuhan as an example,a stability analysis is made with digital-analogue of ANSYS finite element software.The stress field of high rock side slope,distribution of displacement field and the stress of anti-skid piles are compared and analyzed in case of different support schemes.The results show that horizontal displacement of side slope is reduced apparently by frame girder and anchor rod support,while the stability of high rock side slope is increased.
