Based on reinforced soil retaining wall structure of whole rigid panel,deformation of reinforced aeolian sand retaining wall,strain distribution of geosynthetics and working mechanism of reinforced aeolian sand retaining wall were researched.

According to the physical and mechanical speciality of reinforced aeolian sand and by the way of elasto-plasticiy FEA to study the reinforced aeolian sands strength and deformation performance,and adopt the geo-grid as the reinforcement material strength the sand soil that gathered by wind and increase the strength and stability of soil body,so as to improve the soil strength and stablity.

Indoor model tests have been made for the study of the uplift load of spread foundation on reinforced aeolian sand subgrade.

After studing test projects,indoor model uplift tests on the spread foundation of reinforced aeolian sand subgrade have been done.

With the application and study on the reinforced retaining wall in highway construction,the study of the reinforced mechanism and the mechanics response of the reinforced retaining wall are paid more attention.

This paper studies the reinforcing mechanism of geotextile with the aid of centrifugal modelling test and FEM as well as practical application of geotextile to reinforced retaining walls.

Design of geotextile-reinforced retaining wall on weak foundation;

Experimental study on reinforced retaining wall by artificial textile on super-soft soil foundation;

Field study and analysis of reinforced earth wall for expansive soils;

Based on the reinforced earth wall project of a transformer substation,field test was conducted.
