摘 要: 针对公路岩质高边坡在公路建设卸荷过程中所产生的影响,采用有限元数值模拟技术对边坡稳定性进行分析。通过实例计算分析,得出未防护边坡的稳定性较差,应用锚杆框架梁支护的边坡稳定性较好,尤其在降雨情况下该防护技术起到了很好的作用;现场试验的钢筋应力计与混凝土应变计的数据显示,边坡防护时处于弹性运营范围,增设锚杆框架梁的防护措施在边坡运营中得到了很好的效果。 Finite element analysis was employed to study the effect of unloading on the stability of highway rock slope. Calculation results showed that slope unprotected was unstable, while the stability of the slope protected with anchor frame beam was raised, especially in rainfalls. The data measured by the reinforcement stress gauges and concrete strain gauges showed that the operation of slope was in elastic range and the protection measure, such as anchor bolt frame, used in highway rock slope was effective for engineering reinforcement.
