摘要
将锚索抗滑桩看作由锚索和抗滑桩共同组成的支挡结构系统,同时,将其中的抗滑桩视为搁置在弹性地基上的梁,并将锚索拉力作为集中力加在抗滑桩上;应用初参数法分别建立了滑面上下基床参数为同一常数和滑面上下基床参数为不同常数时的计算锚索抗滑桩弯矩、剪力、挠度和转角的初参数公式。以某滑坡治理工程中采用的锚索抗滑桩为例,对其内力进行了计算。
Anchor anti-slide pile is regarded as a kind of retaining structures made up of anti-slide pile and anchor, at the same time, the anti-slide pile of this structure is also regarded as the beam laid on the elastic foundation and the tension of anchor is conducted as a concentrated force loaded on the pile. Applying the initial parameter method, an initial parameter method formula on how to calculate the internal force of anchor anti-slide pile is set up respectively when the foundation coefficient of up and down sliding surfaces is a same constant and the coefficient are different constants. Comparing this method with the existing methods, it has such advantages as clear, ocular and suitable for programming. In the end, the internal force of anti-slide piles of a landslide control case is calculated using this method, meantime, the sketch is drawn about the moment, shearing force and the side clay resistance strength
