摘要:
在改进的非饱和三轴仪上针对洛阳地区非饱和土开展强度试验研究,结果表明:粘聚力趋势角相对内摩擦角有更高的变化率、更大的变化范围,似粘聚力和随着饱和度的降低而快速增长。全面地考虑土中力学因素及土体结构影响的强度、变形理论研究是目前非饱和土土力学理论研究领域中的难点,对此用饱和度作控制变量建立了基于饱和度的非饱和土广义双变量强度理论,研究表明这一与以往理论建立思想有所不同的尝试对考虑土中力学因素、土体结构性的影响是有效的。
Abstract:
The strengh experiment is carried out to the unsaturated soil of Luoyang area on the improved triaxial apparatus.The result indicates that the rate and change range of φSr are larger than the ones of φ’,and the values of cSr and φSr fast increases along with the fall of Sr.It is difficult to study the strength theory of unsaturated soil,in which the influences of mechanical factors and structure of soil on the strength and deformation theory are comprehensively considered.The generalized dual-variable strength theory of unsaturated soil is established based on the saturation which is taken as a control variable.The conclusion indicates that the attempt is effective,which is different from the other theories because of consideration of the influences of mechanical factors and structure of soil.
