Advances in research of rock masses containing discontinuous joints in direct shear test;

Effect of effective shearing area on result of direct shear tests;

Research on direct shear test and pullout test between clay and geotextile;

Investigation on reinforcement-sand-clay layer system using direct-shear test;

In this paper,systematic direct-shear tests in large direct-shear apparatus were carried out for the clay reinforced by geobelt under different normal stresses and water contents.

In order to determine the stress-strain relations and performance parameters of graded soil during the simulation analysis of vibration drum and soil model,the dynamic triaxial and direct-shear tests are performed on graded soil to analyze its strength parameters and the stress-strain relationship.

Improvement study of lab large-scale direct shear test of rock-soil aggregate mixture;

On the shear tests of the single point method rock mass structures

It introduces the detect methods of the two interface between reinfor cements and soils parameter of pull out test and shear test,represents the main factors of affecting the tests and the select standard of the test methods,and researches the share character of the interface between reinforcements and sand clays and the interface between reinforcements and clay soils.
