A simple and robust nonlinear dilatation constitutive model with clear mechanics concept is introduced, and the stiffness coefficient matrix of constitutive relationship is presented. A kind of coarsed-grained soil is co...

In recent years, granular soil is widely used in more and more earth-rockfill dams and high-filled projects being built. However, particle crushing of granular soil can not be ignored as the particle crushing of granular...

Eight large-scale triaxial tests on coarse-grained soil with different lithologies are carried out. The effects of gradation on strength, deformation, dilatancy and particle breakage characteristics of coarse-grained soi...

According to the fractal theory, the fractal distribution formula of gradation for rockfill materials is deduced. The field gradation data of six dams with clay core and five 200 m-high CFRDs are used to verify the relev...

The irrigation method can directly detect the density of the filling body. It has the merits of simple principle and easy to use, so it is widely used in the quality inspection of the filling materials of earth rock fill...

ABSTRACT In the Amazon, the growing demand for fish has been boosting the expansion of fish farms. However, the intensification of cultivation can generate disequilibrium in the parasite-host environment, predisposing fi...

The key point to the safety assessment of concrete face rockfill dams is the effective layout of seepage monitoring facilities and the collection and analysis of monitoring data. Through the analysis of the dam monitorin...

Abstract The aim of the present study was to investigate the occurrence of N. caninum associated with abortions of dairy cattle from Santa Catarina state, southern Brazil by using enzyme-linked immunosorbent assay (ELISA...

The triaxial permeability tests on cement-gravel soil are conducted using the improved triaxial test apparatus. Various factors including cement mixing ratio, gravel content, degree of compaction and seepage pressure tha...

The safety of core wall type rockfill dams during reservoir impounding is greatly affected by the slaking deformation of upstream shell materials. The slaking deformation of the rockfill materials is analyzed using the t...
