摘要
边坡防护中的锚固格构梁多采用Winkler假设计算内力,设计者通常忽略了边坡岩土体和格构之间摩擦阻力的影响。摩擦阻力对于预应力而言较小,但确实存在,在未加预应力锚固格构梁中不应忽略。本文提出了一种简单有效的计算方法,并结合工程实例,使格构梁的设计得以优化。
Frame beams in slope protection are often analyzed for internal forces using the Winkler model. Designers usually overlook the frictional force between the frame beam and the slope. Even though the frictional resistance is much smaller than the pre-stress of an anchor bolt, it does exist. Therefore, it should not be ignored in a non-pre-stressed anchor bolt frame. This paper introduces a simple and effective method for calculating internal force with a case study. The results show that this method can help optimize design of the frame beam.
