Abstract


The strength theory research is extremely complex and very wide range of topics , as research content, not only has important theoretical significance, but there is significant value in engineering applications . Based on the lack of existing strength theory , to carry out three shear unified strength theory of theoretical analysis and experimental validation studies , the main contents of this paper : (1) on the basis of research results at home and abroad , from the reasonable limit surface non- convexity, principal stress state , the state of plane stress sigma - τ complex stress state in such areas as reasonable discussion of the three shear unified strength theory , draw the principal stress space three-dimensional limit surface , perfect triple shear unified theoretical system . ( 2 ) access to a large number of domestic and foreign true triaxial test data , to carry out a verification test on all kinds of material shear unified strength theory ; drawing main stress space limit surface ; and true triaxial test data and shear unified strength theory theoretical limit surface fitting analysis . Summarizes the factors that affect the strength of the material parameter selection , validation and broad applicability of the three shear unified strength theory . (3 ) use of Xi'an University of true triaxial apparatus to carry out the true triaxial test on remolded loess analysis remolded loess under true triaxial state of stress-strain relationship , describing the destruction of the sample form and mechanism analysis . Based on the strength and deformation characteristics of geomaterials , to carry out remodeling strength characteristics of loess . Draw the the pi plane limit surface and plotting true triaxial test data points , the test data with three shear unified strength theory theoretical limit surface fitting analysis obtained remolded loess intensity change ( yield and destruction ) law , and further validate three shear unified strength theory .
