【摘要】 对锚索抗滑桩设计中的合理间距、桩的嵌固深度、抗滑桩内力和变形计算等问题进行了探讨。指出对于锚索抗滑桩系统来说,最小间距应根据桩和锚索的间距综合考虑;对于锚索抗滑桩的嵌固深度,只要使其满足桩周地基承载力的要求即可,仅靠增加桩的嵌固深度,对改善桩身内力和变位的意义并不大。分析了当前计算锚索抗滑桩内力和变形的几种主要方法,讨论了影响锚索抗滑桩内力和变形分布形式的主要因素以及对锚索抗滑桩进行全局优化设计的思路。更多还原

【Abstract】 Reasonable space between piles,the built-in depth,the internal force and the deformation of piles in designing the anchor anti-slide piles is studied.It is point out that the minimum space must be comprehensive considered on the basis of the space between piles and anchors.For its built-in depth,it is not significance to improve the internal force and deformation only through adding the built-in depth.So,it can be satisfied with requirements for that if ground-bearing capacity around piles can be satisfied in that way.Last,some current principal methods about calculating internal force and deformation of anchor anti-slide piles is analyzed,and some main factors effecting shape distributed of internal force and deformation,and overall situation optimization design of anchor anti-slide piles is discussed.更多还原
