摘　　要：为提高公路路堑边坡的稳定性,根据地质调查结果,开展预应力锚杆框架梁设计,并采用数值模拟的方式检验设计方案的合理性。通过边坡稳定性分析,合理确定预应力锚杆框架梁设计参数。建立计算模型,对公路边坡防护前后的应力应变进行计算,分析得出:采用预应力锚杆框架梁防护后,边坡的应力和应变值均较小,未产生明显塑性变形,结合施工现场监测结果,认为设计方案具有可行性。In order to improve the stability of highway cutting slope,based on the geological survey results,the design of prestressed anchor rod frame beam is carried out,and the rationality of the design scheme is verified through the numerical simulation.The design parameters of prestressed anchor rod frame beam are reasonably determined through the slope stability analysis.The stress and strain of the highway slope before and after protection are calculated by establishing the calculation model.The analysis shows that:after using the prestressed anchor rod frame beam protection,the stress and strain values of the slope are relatively small,with no significant plastic deformation.In combination with the monitoring results of the construction site,it is believed that the design scheme is feasible.
