摘要
本文从分析护坡桩常见的破坏方式及原因入手，提出在设计中应对一些主要问题根据不同的条件具体进行考虑，并对灌注式护坡桩的设计方法进行了探讨。文章首先分析了护坡桩五种常见的破坏方式及原因，并按悬臂式、单锚浅埋、单锚深埋三种类型探讨，论述了灌注式护坡桩的设计方法，同时对基底隆起问题及锚杆设计问题进行了分析。
Grouting slope-retaining pile(GSRP),with good qualities,is more and moreapplied to the retaining construction of deep foundation. But in practice,quite a number ofGSRP cracked or deformed to some degree owing to inadequate design.It is imperative tomake further research and find the solutions.In this paper, five types of regular crack or deformation of GRSP and the causes wereanalysized, and the design methods of suspending GRSP, shallow-buried monoanchorGRSP and deep-buried monoanchor GRSP, which were managed to prevent crack ordeformation. were dealt with respectively. In addition, the problems of basement uplift andanchor beam(bar)design were discussed.
