滇东南构造溶蚀侵蚀低中山地貌区红黏土强度特性研究

Study on Strength Characteristics of Red Clay in Low Mountain Landform Area of Southwest China

红黏土在路基施工过程中具有难以压实的特点,一般不宜于直接用于路用填筑,但部分红黏土各项力学性能具备作为路基填料的要求。为了研究云南红黏土的力学特性,开展了不同含水率下的承载比、回弹模量的室内试验。各项试验数据可作为滇东南构造溶蚀侵蚀低中山地貌区红黏土路基填筑过程中的质量控制要点的相关依据。

Red clay has the characteristic of difficult compaction in the roadbed construction process,which is not generally suitable for road filling,but some of the mechanical properties of red clay can meet roadbed filler requirements. In order to study the mechanical properties of Yunnan red clay,this paper carried out in door tests under different water content of the bearing ratio and the elastic modulus. The experimental data can be used as the basis for the quality control of the red clay roadbed in the low mountain landscape in the southeastern Yunnan.
