The filter cake on the tunnel face has a significant influence on project of the slurry-driven shield. During the excavation, only permeable filter cake is allowed to form because the rotating speed of cutter wheel is fast. Through the filter cake, the water of slurry will infiltrate into the soil. The water enhances the hydraulic head and the risk the failure of tunnel face. In order to determ…

Packing model of aggregate is a very important issue in gradation design and research on asphalt mixture. The packing characteristics of coarse aggregate and fine aggregate can affect the skeleton and volumetric parameters, such as VMA (Void in Mineral Aggregate), of asphalt mixture respectively. In this study, based on the ideal packing model of aggregate, the 2?D packing model which is a rand…
The Projects NCHRP9?19 and 9-29 in the USA have researched and developed SPT (Simple Performance Test), which can be used to test asphalt mixture's dynamic modulus, static creep and permanent deformation under repeated loading and analyze the visco?elasticity of asphalt mixture. This article, based on the modified Burgers model and Boltzmann superposition principle, figures out visco?elasticity…
