基于多层次灰色评价法的钻孔灌注桩施工风险评价

Risk Assessment of Bored Piles Construction Based on the Method of Multilevel Grey Evaluation

钻孔灌注桩作为桥梁、市政高架桥桩基础最为常见的一种施工方式,其自身存在较大的质量、安全风险因素。在建立符合实际情况的钻孔灌注桩施工风险评价指标的基础上,基于层次分析法和灰色评价法,将定性与定量计算合理的结合在一起,并对天津市外环线调线工程的钻孔灌注桩施工风险进行评价,得到了科学的,有预见性的结论,为桩基础施工提供了一种有效的评价方法。

Bored piles as a most common Construction methods of Bridges, viaducts murticipal pile foundation,it exist large risk factor of quality and safety. On the base of Bored piles construction risk assessment for realistic situation ,and base on AHP and Grey Evaluation analysis,it corn hines qualitative and quantitative calculation reasonably,and estimate the risk of Bored piles in project of line changed in Tianjin city Outer Ring Road, the conclusion proved scientific and predictable,and it provide Bored piles construction with a effective evaluation method.
