摘要
通过有限元数值模拟方法 ,对全长粘结型锚杆加固的均质岩石开挖边坡进行了数值计算 ,并分析研究了加锚边坡的应力与变形特性和全长粘结式锚杆轴力分布规律 ,提出了一种简单实用确定边坡可能滑动面的方法 ,并且指出了在边坡锚杆支护设计中应注意的一些问题。
The homogeneous rock slope reinforced with wholly grouted anchor bar is simulated by FEM. The deformation and stress of homogeneous rock slope reinforced with wholly grouted anchor bar and axial stress of grouted anchor bar is studied and discussed. This paper puts forward a method used to ascertain sliding surface of slope and the problems in designing reinforcement of homogeneous rock slope with wholly grouted anchor bar are pointed out.
