摘要
预应力锚索在边坡工程中的运用非常广泛,锚固角度的选择直接关系到边坡的整体稳定性。结合了"垂直论"、"平行论"和"最优论",通过有限元数值模拟的方法,从锚固力、安全系数和经济因素等方面,进行了综合分析和论证,提出了实际最优锚固角的概念,比理论最优锚固角值更加切合实际。
Prestressed anchor cable is widely used in slope engineering, the choice of the anchorage angle is directly related to the overall stability of the slope. Combines the theory of 'vertical theory', 'parallel theory' and 'optimal theory', through the finite element numerical simulation method, the anchoring force, safety factor and economic factor, etc., has carried on the comprehensive analysis and argument, puts forward the concept of the actual optimal anchorage angle, more practical than theoretical optimal anchorage angle value.
