某高速公路黄土湿陷敏感性分析

On analysis of collapse settlement sensibility of some express road

通过对室内外试验数据成果的分析,用数理统计方法和Q型聚类方法,系统研究了不同深度黄土湿陷系数随天然含水量、超塑含水量和干密度等变化规律,建立了该地区湿陷系数与其主要影响因素间的经验方程,为该区黄土的理论研究和工程实践提供了科学依据。

According to the analysis of the data results of indoor and outdoor experiments,the paper researches the change rules for the loess collapsible coefficient along with the natural water content,the over-plastic water content and dry density by mathematical statistics and Q clustering method, and establishes the experience formula of the collapsible coefficient and main influential factors,so as to provide scientific reference for the theoretic research and project practice.
