摘要
基于模糊集理论,结合湖南省某跨渠桥桩基工程地质勘察资料,建立了桥梁基桩桩端溶洞顶板稳定性的模糊二级综合评判模型与模糊极限平衡分析模型,并分别解决了相应的模糊分析参数构造与评价方法问题,最后分别应用于某一实际工程,分析结论基本相同且与实际情况符合良好,为岩溶区桥梁基桩桩端溶洞顶板稳定性评价提供了新的思路和方法。
Based on the fuzzy sets theory, combined with the exploration data of karst of a canal-spanning bridge in Hunan province, the model of two-stage fuzzy synthetic judgment and the fuzzy limit-equilibrium-analysis model for the cave roof stability under pile tip are set up. The corresponding fuzzy sets of analysis parameters are constructed and evaluation methods are developed as well. Finally, these two methods are applied to an engineering example showing that these methods are effective for stability evaluation of cave roof under pile tip in karst region.
