Construction technology and quality control method of rock-fill embankment;

Non-linear constitutive model for rock-fill embankment;

From the aspect of rock-fill embankment s engineering properties on construction,detection and large particle size fillers,review and conclude the domestic and foreign rock-fill embankment construction technology,and view the development trend of rock-fill embankment construction technology.

Settlement calculation of the toe-shooting embankment;

Application of neural network in settlement calculation of rock-filled embankment;

Experiment Study on Rock-filled Embankment & Model Parameter s Back Analysis on Rock-filled Object;

The rock-filled embankment took one kind of ideal embankment form to obtain the widespread application.

Study on constitutive model and its parameter’s back analysis of creep deformation for the high rockfill embankment and their application;

Along with the rapid development of higher grade highway construction in west of China, the rockfill embankment has become a major form of the expressway in mountainous area.

Programmed large-scale numerical analysis program for project of rockfill embankment,in the program,the DDA model of embankment is built with random generation and diameter control and natural stacking of block;it is simulated that extending and rolling embankment layer by layer and the deformation of embankment after construction.

The subgrade filled with stones(diameter≥40 mm,content≥70%) is called filling-stone subgrade.

Basing on the summary of history, research fields of compact mechanism and effect test of filling-stone subgrade and existing problems in Geotechnical Engineering field, the influence factor of compaction effect and every kind of examination method of quantity examine on the spot of filling-stone subgrade are introduced.
