武广客运专线非饱和红粘土动三轴试验成果及分析

The Achievement and Analysis on the Dynamic Triaxial Test of Unsaturated Red Clay for Wuhan-Guangzhou Special Passenger Railway

从武广客专线有代表性的红粘土地段——泉口、咸宁钻孔取样，并对其进行了动三轴试验及分析，获得了这2个工点的非饱和红粘土在不同固结比、不同围压条件下的动剪应力-破坏震次的关系曲线、动应力、动剪强度指标、动弹性模量及相关试验常数，这对武广客运专线非饱和红粘土地段的设计具有参考作用。

Samples are taken from Quankou and Xianning City by drilling which is a representive red clay of Wu Guang special passenger railway. After the analysis dynamic triaxial test on these samples, it get different concretion ratio of unsaturation red clay from 2 labor spots, relation curve of different surround pressure condition lower move shear stress destroy, dynamic stresses, scissors intensity index, dynamic elastic modulus and relevance experiment constant item, which have the reference effect to the design for unsaturation red clay section of Wu Guang special passenger railway.
