The application model of 3D cadastre in practical registration for real estate in China

Since the introduction of the concept of 3D cadastre, a great many of significant research results have been done. To promote the development of 3D cadatre, 3D cadastre working group sponsored by International Federation Surveyors (FIG) commissions 3 and 7 was organized by Delft University of Technology in 2001. This working group provides a...

Mechanical and chloride permeability properties of coarse fibre reinforced concrete

Synthetic fibers have been widely studied as reinforcing materials to increase the mechanical and durability properties of concrete. According to its diameter, fibers can be categorized as micro and macro (or coarse) fibers. As most research focuses on the mechanical properties of fiber reinforced concrete, its chloride permeability properties...

Scale of Fluctuation for Geotechnical Probabilistic Analysis

In the past few years, random field theory has been increasingly used to model the inherent soil variability. The scale of fluctuation is one of the important parameters describing a stationary random field. In this study, the factors affecting an accurate estimation of the scale of fluctuation were studied with numerical experiments to show how...

Preferential concentration of particles in compressible turbulence

The behavior of particles in compressible turbulence has been seldom investigated to date despite its importance in many natural and industrial flows. Direct numerical simulations of particle-laden compressible isotropic turbulence are performed to study the preferential concentration of particles and the underling mechanisms. It turns out that...
