中文摘要	基于统一强度理论,以某高速公路路基边坡的典型断面为例,运用刚体极限平衡理论中的毕肖普简化法进行计算,得到不同的统一强度理论参数、不同的双剪应力状态参数与边坡稳定系数之间的关系。在此基础上,讨论了边坡问题的强度理论效应。通过分析可知,中间主应力在边坡稳定性分析中不容忽视。实际工程中,应根据具体边坡的岩土特征及应力状态确定统一强度理论参数和双剪应力状态参数,确切地反映岩土强度特性,界定稳定系数的上下限范围,有效地发挥材料的强度潜能,节约工程费用。; Based on the unified strength theories,taking a typical section of some highway roadbed slope as an example,and with Bishop's simplified method of limit equilibrium theories of rigid body,obtained the relationship of different parameters of unified strength theories,different parameters of twin-shear stress state and coefficient of the stability of slope.On the basis of research result,the effect of strength theories is discussed.By analysis,it can be concluded that the effect of intermediate principal stress in the stability of slope analysis shouldn't be neglected.In actual project,we should determine the parameters of unified strength theories and the parameters of twin-shear stress state according to the characteristics of geotechnical and the stress state of concrete slope,reflect the strength characteristics of geotechnical exactly,and limit the scope of stability coefficient,exert the potential of material effectively,thus,the project expense could be saved.
