Zhang, L. (author), Yan, W.M. (author)Soil slopes are generally unsaturated in which the soil-water characteristic curve (SWCC) plays an important role in its hydro-mechanical response. The commonly used Mohr-Coulomb failure criterion in saturated soil mechanics could be extended to take SWCC into account which is then able to determine the shear strength of unsaturated soil. Like...conference paper 2015

Chen, H.X. (author), Zhang, L.M. (author)Shallow slope failures are one of the most frequent geological hazards in mountainous areas, which pose great danger to people and properties in affected areas. This paper presents a cell-based platform for quantitative risk assessment for shallow slope failures at a regional scale. There are five components in this platform; namely, a digital...conference paper 2015

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...conference paper 2015

The validity of the recently proposed hypothesis that the influence of large-scale motions on the near-wall turbulence is quasisteady is investigated by quantitative comparisons with the data obtained by direct numerical simulations of a turbulent channel flow. Large-scale motions are filtered by a Fourier cut-off filter multi-objectively...conference paper 2015

Compressible Rayleigh-Taylor turbulent mixing (CRTM) induced by Rayleigh-Taylor instability occurs when a compressible fluid of heavy density is accelerated or supported against gravity by a compressible fluid of light density, and is of fundamental importance in applications from combustion, to inertial confinement fusion, and to astrophysics....conference paper 2015

Xiong, Q. (author), Zhu, Q. (author), Zlatanova, S. (author), Du, Z. (author), Zhang, Y. (author), Zeng, L. (author)Indoor navigation is increasingly widespread in complex indoor environments, and indoor path planning is the most important part of indoor navigation. Path planning generally refers to finding the most suitable path connecting two locations, while avoiding collision with obstacles. However, it is a fundamental problem, especially for 3D complex...conference paper 2015

Cats, O. (author), Zhang, C. (author), Nissan, A. (author)Parking pricing policies can be used as a policy instrument to steer the parking market and reduce the externalities caused by traffic in general and parking in particular. A more efficient management of parking demand can improve the utilization of the limited parking capacity at high-demand areas. Even though parking policies are often a topic...conference paper 2015

Zhang, Y. (author), Ye, G. (author)Due to environmental (low CO2 emission) and economic benefit, supplementary cementitious materials (SCMs) have been widely used in reinforced concrete structures. However, the question from engineering practice is to which extend these blended mixtures do meet the future durability criteria. Chloride ingression is nowadays considered as the main...conference paper 2015

Li, Zi Ru (author), Zhang, Guang Ming (author), He, Wei Dong (author), van Terwisga, T.J.C. (author)In this paper, the unsteady cavitation phenomena on a NACA0015 hydrofoil is numerically simulated by unsteady Reynolds-Averaged Navier-Stokes (URANS) method and Large Eddy Simulation (LES) in single-fluid approaches to multiphase modelling, respectively. It is observed that the large-scale structures and characteristic periodic shedding...conference paper 2015

Zhang, Y. (author), Ye, G. (author)Concrete is seldom saturated due to its self-desiccation. Even the submerged concrete structures may remain unsaturated for quite a long time. It has been reported the saturation level of pore solution has significant effect on species penetration. However, very little work was proposed regarding the transport properties and serviceability of...conference paper 2014
