层次分析法在嵌岩灌注桩施工风险分析中的应用

Application of Analytic Hierarchy Process in Risk Analysis of Constructing Embedded Pile

介绍层次分析法原理,并将其用于嵌岩灌注桩施工风险分析。运用几何平均法进行权重计算,建立嵌岩灌注桩风险评价理论体系。以重庆市云阳汽车客运中心嵌岩灌注桩施工风险为实例,对施工过程中的风险因素进行权重排序。

This paper introduces the principle of AHP （analytic hierarchy process） and applies it in risk analysis of the construction of cast - in - situ rock - socketed piles. The geometric average method is adopted to calculate the weight first, and establish the risk assessment theory system of cast -in -situ rock -socketed pile. Guided by the construction of science and technology project in Chongqing, and we take the construction risk of embedded pile in Yunyang transportation hub project as an example to weigh the risk factors in the construction process.
