武广客运专线非饱和红粘土三轴试验成果及分析

The Achievement and Analysis on the Triaxial Tests of Non-Saturated Red Clay of the Railway Line for Passenger Traffic from Wuhan to Guangzhou

从武广客运专线的泉口、咸宁、耒阳3个工点的不同深度的非饱和红粘土地基中钻探取样,分别进行不固结不排水、固结不排水、固结排水三轴试验,获得了3个工点的非饱和红粘土的粘聚力、内摩擦角的试验值,为武广客运专线红粘土地段的设计提供了设计指标。

Getting drilling samples of different depths of non-saturated red clay ground from the three work places like Quankou, Xianning and Leiyang of the railway line for passenger traffic from Wuhan to Guangzhou. unconsolidatedundrained,, consolidated undrained and consolidated drained triaxial tests to the samples are carried on respectively, and the experimental value of the non-saturated red clay＇s cohesion and the angle of internal friction of these three work places are also obtained, which has provided the design ,target of red clay sector design of the railway line for passenger traffic from Wuhan to Guangzhou.
