Research on Interaction between the Embedded Anti-Slide Piles and the Frame Beam with Pre-Stressed Anchors
In recent years, due to its own characteristics of the embedded anti slide pile in the slope support, it is widespread application in the slope support, becoming a main way of the slope support. InExpand

The Development of the Plastic Theory of Geomaterial
The former constitutive models of geomaterial are always based on classical theory of plasticity, such as the famous Cam-Clay model. However, a large number of geotechnical tests show that theExpand
The Dynamic Constitutive Model of Geomaterial
Geomaterial dynamic constitutive model (or dynamic stress–strain relationship) is the foundation for understanding the dynamic behaviors of geomaterial or geomaterial structure, which is under theExpand
The Static Elastoplastic Model for Geomaterial
Elastoplastic theory assumes that elastic deformation coexists with plastic deformation. The total strain can be divided into two parts: elastic and plastic.
Gradient-Dependent Damage Constitutive: The Second-Order Gradient Damage Model
When the strain tensor, the scalar damage quantity and the Laplacian thereof serve as the state variables of Helmholtz free energy, the general expressions of elasticity-gradient damage constitutiveExpand
The Elastic Model of Geomaterial
The elastic model of geomaterial is the mechanical model based on the elastic theory. There are two purposes to study the elastic model of geomaterial: one is to describe the elastic part ofExpand
Several basic problems in plastic theory of geomaterials
Based on the basic mechanical properties of geomaterials, it was proven that the Drucker Postulate and the classical theory of plasticity can not be applied to geomaterials. Moreover, several basicExpand
