Dynamic interaction of wheel-rail is studied by using DSAS software when Blue-Arrow power car, trail car,"SS8" locomotive and passenger car with "209" bogies pass through a curve with severe rail oblique crack in Guang-Shen railway, respectively. Results of the above cases are compared and analyzed. Based on these results, effect of track structure parameter and train speed on dynamic interaction of wheel and rail in curve track is discussed, and a set of synthetic and effective technology measure which eliminates or releases rail oblique crack is put forward, The results can be expected to provide theoretic basis and guidance for engineering practice.

Results indicated that according to the different newly increased cultivated land rate, land consolidation projects on the district or county level could be divided into four categories: land consolidation, cland consolidation and exploitation, land development and consolidation, land development. While according to the investment per unit area on newly increased cultivated land, it could also be divided into four categories: high investment, reasonable investment, partial low investment and low investment. Correlating curve type among the investment per unit area in newly increased cultivated land, average annual growth rate of GDP and average annual growth rate of per capita GDP was a compound one. Correlations among newly increased cultivated land investment per unit area and annual growth rate of per capita GDP, annual growth rate of per capita GDP and other economic development indexes showed an "S" changing tendency curve.
