| 摘 要： | 煤系地层路基边坡横观各向同性岩体与加固防护措施的相互作用机制比较复杂，结合晴兴线煤系地层高速公路路基边坡工程，对现场样品的横观各向同性岩样进行了单轴压缩实验，确定弹性特征的参数，并通过有限元方法分析了煤系地层岩体横观各向同性边坡与预应力锚索框架梁的相互作用影响，为煤系地层横观各向同性岩石边坡的预应力框架梁支护设计提供了借鉴。

| Abstract: | The rock of slopes is still regarded as isotropy mass in coal-bearing strata roadbeds. The interaction between the isotropy rock mass and reinforced structure is complex. Tightly combined with engineering geology of the slope at Qing-Xing Expressway Project, this paper intends for the uniaxial compression laboratory test for sampled from the situ to determine the index of describing elasticity characteristics of isotropic rock, and the interaction between rock mass isotropy of slope and pre-stressed anchor cable with frame beam was researched by the finite element analysis, some useful reference information on pre-stressed anchor cable with frame beam supporting for isotropy rock slope was provided in coalbearing strata. |
