Stability analysis of subgrade cave roofs in karst region

, 2008
According to the engineering features of subgrade cave roof in karst region, the clamped beam model of subgrade cave roof in karst region was set up. Based on the catastrophe theory, the cusp catastrophe model for bearing capacity of subgrade cave roof ...

Subgrade characterization for highway pavement design. [PDF]

State Study 131Subgrade soil characterization expressed in terms of Resilient Modulus (MR) has become crucial for pavement design. For a new design, MRvalues are generally obtained by conducting repeated triaxial tests on reconstituted/undisturbed ...
