Interior stablility analysis method of soil-nailed structure based on empirical genetic-simplex algorithm;

Based on the land style quality structure,quantity structure,spatial structure and land use structure,the land structure and its characters in the gully area of Loess Plateau were analyzed.

On the basis of dividing and evaluating the land style,characteristics and problems of the land structure (including the land style structure, the land resource structure, the land spatial structure and land use structure) , were analyzed and opinions for developing and reasonable using the land resource in Ansai county are suggested.

Thus, There is important theroretical significance and practical value in study on land structure in order to exploit it rationally and protect it effectively as well as to gain maximum economic, ecological and social benefits.

FT IR Study of the Influence of Grinding on Clay Structure;

The dynamic interaction of pile-soil-structure in liquefiable site,especially,the seismic response on pile,are studied with the method of whole dynamic finite elements under seismic condition.

With the finite element method of complete dynamic interaction of pile-soil-structure combined with a typical case study in engineering,a finite element analysis model was created with a visco-elastic boundary set at the artificially truncated boundary to study the effects of soil characteristics on seismic responses of foun- dation piles for the case of horizontal seismic loads.
