摘要
以西安地区黄土为试验材料,通过室内三轴试验,分析黄土在不同含水量下的应力应变关系,得出了土在不同含水量下的应力应变关系.并通过对应力应变关系分析,得到黄土结构性和强度主要受初始含水量、围压和密度等的影响,这些因素决定黄土的应力应变关系和黄土破坏的形式.
In this paper,the author takes ocher of Xi＇an region as experimental material,analyzes ocher＇s stress-strain relationship in different level through indoor triaxial experiment,and acquires earth＇s stress-strain relationship in different level of water content.Meanwhile,the author through analyzing stress-strain relationship finds that ocher＇s structure and intensity were mainly affected by factors like primitive water content,surrounding pressure and density which determine ocher＇s stress-strain relationship and destruction formation.
