Because the grids designed are self adaptive at the boundaries and are denser where the water depth changes rapidly, this 3 d baroclinic model can be used to solve the difficult problem of calculating circulation on the continental slope.

The finite element model for contact analysis between roller and tyre under oblique contact status was established,the 3D contact finite element modeling program between roller and tyre under mixed coordinate was developed.

The character of the oblique contact model between kiln roller and tyre was studied,the build-up procedure of oblique contact model between kiln roller and tyre was developed,which is apt to the finite element analysis of roller and tyre under the condition of any load,load rate,oblique angle.

In situ engineering tests on MSW slope compaction effects at Xiaping sanitary landfill in Shenzhen;

In order to thoroughly study the spatial strut-and-tie theory on the punching failure of pile caps, two critical problems, value about end cross dimension of strut and calculation on strut strength, have been carried out based on the literatures and the research results from author.
