考虑中主应力影响的吹填土结构强度研究
A study of the structure strength of dredger fill considering the effect of intermediate principal stress
摘要
Abstract
Based on the true triaxial test on soft dredger fill in Tianjin, this paper examines the change in soil structural strength under three-dimension compression. The results indicate that the structure yield stress and the structure strength have nonlinear changes with the increase of the intermediate principal stress. The peak value appears when the value b is in the range of 0. 50 to 0. 75 , the strain corresponding with the structure yield stress decreases with the growth of the intermediate principal stress. Under the condition of three-dimension compression, swelling deformation goes against the maintenance of the structure while the compression deformation is on the contrary.关键词
