Using high resolution N-body simulations, we studied the distribution of formation-redshift of dark matter haloes with large span of mass and found that all of the 3 kinds of theoretical models including EPS theory can not explain well the simulation results. This indicates that the theoretical conditional mass function of haloes needs further improvement.

Based on a thorough analysis of the character and mechanism of city-retaining-wall structures, the design theories, construction technology, new wall types and development tendency are deeply discussed. Besides, the characteristics of various types of city retaining wall are discussed, and the usual methods for earth pressure calculation are summarized. For the anchored bar retaining wall, the anti-pulling bearing mechanism of anchored bar is first probed into, from which anti-pullforce computation method are obtained. Combined with quite a few engineering examples and spot tests, the advised design and calculation methods of anchored bar are verified. From the abundant spot measured date, an adjusted hyperbolic model is put forward to determine the anti-pullforce bearing capacity. Furthermore, a new type of H-like block retaining structure is advised with its working mechanism deeply discussed as well.
