| 摘 要： | 本文以抗滑桩桩顶位移变形和滑坡地表变形为研究目标,采用决策树模型分别构成抗滑桩桩顶设计位移量、实测位移量、滑坡地表破坏概率的三个决策方案枝,以及抗滑桩破坏概率分析决策终结点的决策树概率分析模型。从而建立了一种分析抗滑桩可靠性的判断方法。该方法的特点是将桩顶位移变形特点与滑坡地表宏观变形现象相结合,对抗滑桩的可靠性作出综合判断,其结果更具合理性。

| Abstract: | In order to research the displacement of the top of the anti-stide pile and surface deformation of the landslide, this paper introduces decision tree method to build three Decision-making plan branches including designer displacement of the anti-slide pile,the measured displacement,the failure probability of the andslide surface and the probability analysis model of decision tree including decision-making endpoints analyzed by failure probability of anti-slide pile. As a result. , a judgment method to analyze the reliability of anti-slide pile is found. Its specialties are using the deformation features of the top of the anti-slide plie combined with visible deformation phenomenon to estimate the reliability of anti-slide pile synthetically . And its result is more reasonable. |
