黄土结构强度常规三轴试验研究

强度指标是地基工程、边坡工程和地下工程设计的重要参数.对于结构性土体,特别是结构性黄土,更是如此.保持生态环境与水土流失,均与黄土密切相关.基于黄土结构强度极为重要,利用三轴试验,研究了黄土结构强度与含水量、围压的关系.研究结果表明:含水量的增加对于结构强度起着软化作用,围压的加载对结构强度起着强化作用.

Study on Structural Strength of Loess by Conventional Triaxial Test

Strength indicator is important for design of foundation,slope and underground engineerings,and the more so for structural soil mass,especially structural loess.The conservation of ecological environment and soil erosion relate to loess closely.Since the structural strength of loess is important,triaxial test was conducted to study the relations between such strength and water content and confining pressure.The results show that the increasing of water content may soften the structural strength,and the loading of confining pressure may enhance the structural strength.
