The limit analysis method theoretical research and application of earth-retaining wall active soil pressure;

Analytical solution of bearing capacity of around unconfined cube soil using limit analysis method;

Finite element limit analysis method has the advantage of combining numerical analysis method with traditional limit equilibrium methods.

Discussion on ultimate bearing capacity of soils around piles based on limit analysis;

By use of the upper limit theorem of plastic limit analysis and variational principle,the ultimate bearing capacity of anisotropic and non-homogeneous foundation soils were ascertained,and the basic formulas were derived.

Through the introduction of main limit analysis theorem, this paper deduces the calculating equation of highway slope critical height in accordance with the two main stability failure.

Application of upper-bound theorem of limit analysis on Ultimate capacity of embankments on mountain slope foundation;

According to practices experiences in the expressway construction on the mountain region,the effect of some primary factors for the Ultimate capacity of embankments on mountain slope foundation were analyzed by using upper-bound theorem of limit analysis,and some useful .

The upper-bound theorem of limit analysis for such slopes was developed,and the slid face s velocity field of folding line was established.
