	Abstract:Large numbers of cracks were included in rock masses. The initiation, extension, coalescence evolution behaviors of cracks in rock mass, and even fissure water pressure have significant impacts on the strength and stability of fractured rock mass in engineering projects. In this paper, we propose an elasto-brittle constitutive model considering fissure water pressure based on the computer code FLAC3D (Three dimensional Fast Lagrangian Analysis of Continua). This constitutive model is initially validated through a pre-cracked rock-like-material specimen in the laboratory experiments and then proved to actually simulate the initiation, extension and coalescence characteristics of cracks considering fissure water pressure in brittle fractured rock mass. It is concluded that fissure water pressure has obvious and significant effect on the strength and stability of fractured rock mass.

	Abstract:Based on digital image correlation (DIC) method and self-developed code, the global strain field changing and failure properties of rock-like materials with pre-existing double flaws are experimentally studied under uniaxial compression. By theoretical analysis with linear elastic fracture mechanics (LEFM), strain approach proves to be practicable to investigate cracking process. Thus, two types of process zone are defined to discuss the specimen's coalescence evolution at different loading phase. Crack initiation, propagation, and coalescence is a process of process zone development and nucleation. DIC strain field results are studied on meso-level using strain approach. In shear coalescence mode, SPZ (shear process zone) in bridge area coalesces with each other, while TPZ (tensile process zone) grows independently. In general, the paper try to establish the link between microscopic mechanical mechanism and macroscopic mechanical response in flawed rock. Further research should be done to study the cracking process and its effect on rock strength in detail by DIC method.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Series of biaxial compression simulations are carried out to investigate the effects of boundary condition on the deformation of granular materials by using DEM. The parameters used in DEM are validated by the biaxial compression experiments on elliptical steel bars. The effects of boundary condition on the stress-strain relationship are analyzed. And special focus are put in the analysis of particle displacement, particle rotation, void distribution, particle long axis orientation and contact force with the development of deformation.

	Abstract:This paper proposes a prototype of a construction schedule management system based on 4D simulation and information flow technologies. As a branch of Building Information Model (BIM), this system integrates the systems of IDEF0v information flow modeling, Design Structure Matrix (DSM) optimization and Virtual Reality (VR) simulation. Apart from visualize the construction process with 4D simulation, as most normal BIM schedule management systems could, the proposed system could also optimize the construction schedule with the information flow modeling and DSM optimizing, and allow the construction managers to make dynamical adaption and optimization to the schedule according to the differences between planned and real process. This system could help the construction managers supervise and control the construction schedule with information and visualization-based schedule simulation model in the whole process of construction project.?????
