摘要
为了更好地评价砂砾石、黏土混合料的压缩、固结特性,利用不同配合比下的砂砾石混合料和改进的试验仪器进行试验,分析了砂砾石基层材料的单位沉降量、压缩系数、压缩模量以及孔隙比与压力的关系,为此类结构的路面设计或路面结构的非线性分析提供了依据。
ln order to appraise the compression and consolidation features of gravel and clay mixture better, test is carried out with improved instrument under different mix proportions. The unit settlement, compression coefficient, compression modulus and the relation of void ratio and stress of gravel base material are analyzed, which provides basis for the design of pavement with the same structure and the nonlinear analysis of pavement structure.
