公路路基弯沉季节修正系数量化分析

摘要

The difference of subgrade deflection value on unfavorable seasons and practical conditions of the project is analyzed comparatively aiming at the uncertainty of seasonal correction value of subgrade deflection in the current practice and the seasonal correction factor of subgrade deflection is analyzed and quantified through theoretical formula derivation based on engineering practice.The results show that adopting the conjoint analysis method of compactness and water content (consistence) to determine the seasonal correction factor of deflection can better provide true data for the acceptance of subgrade deflection construction.%针对现行规范中路基弯沉季节修正取值的不确定性,对比分析不利季节与工程实际情况下路基弯沉值的差异性.在工程实践基础上,通过理论公式推导分析量化路基弯沉季节修正系数.量化分析结果表明:采用压实度、含水量(稠度)联合分析法来确定弯沉的季节修正系数,能更好地为路基工程弯沉施工验收,提供真实数据.
