The column tests on advection-dispersion are commonly used to measure the contaminant transport parameters in soils. The applicability of boundary conditions for analytical modelling of the column tests is under debate. ...

The deformation properties of CFRD (concrete face rockfill dam) are studied through centrifuge tests by building concrete cover plate on the alluvium foundation. Three centrifugal model tests are conducted for the purpos...

Centrifugal model tests are carried out to simulate the construction and operation of the dike on a soft soil foundation for the purpose of taxiway construction on the seashore. The vertical strip drains are adopted for ...

The previous studies show that acid rain pH significantly affects the leachability of stabilized heavy metals-contaminated soils. The parameters of diffusion coefficient (De) and retardation factor (Rd) are critical for ...

The end restraint can be eliminated by lubrication sample cap to some extent in the conventional triaxial tests. A comparison is made between the conventional triaxial tests and the end friction reduced triaxial tests in...

The earthquake liquefaction is one of the direct causes for unstable ground and damage of upper structure. Therefore, the liquefaction assessment is an important part of anti-seismic investigation in engineering. By taki...

Due to their small thickness, high flexibility and tiny sensing element, the tactile pressure sensors can be used to measure the soil stresses and contact forces between soil particles. Hence, the tactile pressure sensor...

During the past decades, the design of horizontal bearing pipe piles has still referred to that of bored piles, as a result, the conservative design has been found frequently. In order to get the bearing mechanism and pi...

The liquefaction resistant rigid-drainage pile is a new type of pile which can be used in geotechnical earthquake engineering. The pile combines the bearing capacity of rigid pile and the drain-ability of gravel pile. Ba...

The in-situ measurement formula for rock permeability is derived based on the theory of steady gas seepage. A rough judgement method for Darcy seepage in engineering is given based on the Pavlovsky’s Reynolds number fo...

The recharge well with filter layer is a common device using for recharging groundwater on the Jiaodong Peninsula in Shandong Province of China, and composed of recharge well and pool. By analyzing the problems of the ex...

The soft soils can meet the bearing needs of the constructions and infrastructures through the appropriate artificial treatment, and the carbonated MgO-mixing pile method is an innovative foundation treatment technology,...

The methods for loess collapsibility mainly include field immersion testing method and laboratory testing method. A majority of the results of laboratory testing method differ greatly from the engineering practice. The d...

In the paper, a selection of statistical tests for median are presented. In particular, parametric and nonparametric significance tests are considered. In the case of parametric tests the critical regions are constructed...

The stability standards for plate load tests on soft foundation are studied based on the engineering practice. The differences of determing the characteristic values of bearing capacity and the ultimate values of bearing...

The tangent modulus method is a method which is based on the plate loading tests to obtain the tangent modulus of the soil under different load levels, and uses the tangent modulus into the layer-wise summation method fo...

Based on the SMP criterion-based K0 consolidated anisotropic Cam-clay model, an analytical solution to cylindrical cavity expansion for pile installation is derived. This solution incorporates the effects of the initial ...

One of the frequent questions by users of the mixed model function lmer of the lme4 package has been: How can I get p values for the F and t tests for objects returned by lmer? The lmerTest package extends the 'lmerMod' ...

The settling column tests and the vacuum preloading model tests are performed on the waste slurry of a construction site in Shanghai and the additive agent slurry. The sediment and turbidity characteristics of slurries w...

The parameters obtained from the piezocone penetration tests (CPTU) have been widely used for soil profiling and geostratigraphy over the decades. In this study, large amount of CPTU soundings and parallel drilling borin...

A series of triaxial compression tests and true triaxial tests based on discrete element method are conducted numerically to investigate the particle breakage behavior of granular materials under triaxial stress conditio...

Artificial assumptions are needed to set the generalized stress paths in hollow cylinder apparatus (HCA). The resulting limitations to imitate the generalized stress paths in HCA are analyzed. According to the function t...
