摘要
针对捆绑式抗滑桩中最简单适用的两根等直径钻孔桩的组合型式的捆绑桩,应用单棒与捆绑双棒承受侧向力作用下的对比实验成果,考虑设计计算理想状况的假定,采用了强度效能折减方法,以采用了钻孔灌注排桩进行边坡支护的实际工程为算例,对捆绑式抗滑桩结构设计计算进行了初步的探讨,并与钻孔灌注排桩方案的设计计算及效果进行了比较。结果表明由于捆绑式抗滑桩在抵抗弯矩上性能更优越,因此在受力钢筋用量上比钻孔灌注排桩大大节省,有更好的经济效果。
Considering the simplest and applicable trussed slide-resistant pile type composed of two equal-diameter piles,applying the comparative experiment outcome of side-force bearing on single-stick trussed double-sticks,taking account of the assumption of design with ideal situation,adopting intensity efficiency discount method,a real engineering case which applied the bored piles to slope supporting was used to preliminarily analyze the design and calculation method,and compare the effect of two Blue-Print of trussed slide-resistant pile the bored pile.As a result,the Trussed slide-resistant pile is more economical in amount of bearing reinforcing steel bars,and more ascendant.
