| 摘 要： | 以在建的某高速公路典型红层软岩路堑边坡为研究对象,在边坡岩体结构稳定性定性分析的基础上,采用FLAC3D软件对坡体及时加固和滞后加固两种工况下的应力场、坡体变形与位移场、锚杆应力状态和塑性区进行了研究,并分析了加固的时效性．研究结果表明,及时加固较滞后加固可以有效地控制边坡坡体的变形与位移,对保证施工期红层软岩路堑边坡的稳定更为有利．

| Abstract: | A typical red-bed soft rock cutting slope under construction is taken as investiga- tive subject, with the qualitative analysis method to analyze the stability of the slope rock mass structure. The stress field, slope deforming and displacement field, anchor stress state, plastic zone of slope are studied at immediate reinforcement and lag reinforcement two states using FLAC3D software in this paper. The reinforcement of the timeliness is also analyzed. The results show that timely reinforcement is more effective than hysteretic rein- forcement in controlling deformation and disp sure the stability of the red-bed soft rock cutt acement of the slope, and it is better to en- ng slope under construction. |
