Nonlinear elastic model for compacted clay concrete interface

R. R. SHAKIR, Jungao ZHU

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 2,   Pages 187-194 doi: 10.1007/s11709-009-0033-2

Abstract: paper, a nonlinear elastic model was developed to simulate the behavior of compacted clay concrete interfaceThe clay soil used in the test was collected from the “Shuang Jang Kou” earth rockfill dam project.It was found that the behavior of the interface depends on the critical water contents by which two failureThe mathematical relations were then incorporated into the interface model.The verification shows that the proposed model is capable of predicting the interface shear stress versus

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 1,   Pages 85-92 doi: 10.1007/s11709-009-0013-6

Abstract: Tests of interface between compacted clay and concrete were conducted systematically using interfacenormal stress and rough surface on the shear stress-shear displacement relationship of clay-concrete interfaceThe following were concluded in this study: 1) the interface shear sliding dominates the interface shearfailure mechanism may change each other with different water content ratio; 4) the interface shear strengthincreases with increasing water content ratio especially for the case of clay-rough concrete surface interface
