Constructing high-fill embankment over soft soils will lead to a substantial deformation of foundation, therefore it is necessary to strictly monitor the settlement and pore water pressure of the foundation. A high-fill ...

The gassy soil containing entrapped gas bubbles is a special type of unsaturated soils, and the compressibility of air-water mixture in gassy soils cannot be ignored. Based on the conceptual model for small bubbles, the ...

The expansive soils have the tendency to expand in wetting and to shrink in drying. The addition of cement is one of the methods to enhance the engineering properties of such soils. The effects of varying cement contents...

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 HS-Small model, which can reflect the attenuation of shear modulus of soils with strain in tiny strain range, has been gradually utilized in excavation engineering. The laboratory tests using triaxial apparatus, oedo...

Glyphosate is the most used herbicide in Argentina, accounting for 62% of the commercialized pesticides in the market. It is used as a weed controller in no-till systems, and it is also applied in various genetically mod...

An in-site observation station for soils around the ground heat exchanger (GHE) in the operating process of ground source heat pump (GSHP) is installed to monitor the operation performance of GSHP as well as heat and moi...

For the expansive soils of Nanning in Guangxi province of China different drying environments are acquired to test the shrinking characteristics and water retention by setting different temperature and humidity condition...

In order to study the electrical resistivity of oil-contaminated soils, the diesel-contaminated soils and kerosene-contaminated soils with different water contents, oil contents are mixed in the laboratory by hand. The f...

The electrical resistivity method is the main non-destructive method for measuring compaction and moisture migration of the unsaturated soils. The van der Pauw method is a well established technique for measuring the res...

Using specially designed low-temperature resonant column apparatus, change rules of dynamic shear moduli and damping ratio with negative temperature and their computational methods for three soils are investigated. Conce...

Volume changes take place during the fully undrained compression tests on unsaturated soils. It is more difficult to simulate the undrained mechanical behaviors of unsaturated soils than those of saturated soils. In this...

To find a simple and precise settlement calculation method for rigid pile composite foundation is still an urgent problem which is not solved as yet. For the settlement calculation of rigid pile composite foundation in s...

In order to verify the reasonableness of two stress state variables for unsaturated soils and to improve the accuracy of tests, the triaxial apparatus for conventional unsaturated soils has been improved to control the p...

Plants are sophisticated and intelligent natural construction materials. They can be used for enhancing the stability of shallow soil slopes and minimizing surface erosion. It is evident that the use of plants can be low...

Under the framework of bounding surface plasticity and critical state concept, by introducing the disturbed state concept for hardening variables of elastic behavior, structured yield surface, structured bonding adhesive...

Due to the viscosity and easy-cracked characteristics of clay, series problems, such as non-homogeneity, low-saturation and microcracks, exist in the hollow cylinder specimens generally made by using the compaction metho...

The property of the soil in free field is an important influencing factor for the free field seismic response. In the existing studies the soil at local site is supposed to be the single-phase medium or saturated porous ...

Considering the spatial variability of soil properties, a probabilistic evaluation method is proposed for the safety of buildings above tunnels based on the random field theory and the numerical analysis method. The elas...

In order to explore the influences of matrix suction and net confining pressure on the deformation-strength and unloading-reloading modulus of loess, three groups of 27 tests are performed using the unsaturated triaxial ...

The voids behind the tunnel linings seriously affect the interaction between the linings and the surrounding soils, generally in the form of cracking, spalling or even failure, directly affecting the safety of tunnel ope...

The sea sand-mud mixture used as filling material is proposed. The strength parameters and compression performance and permeability of soils are compared and analyzed through laboratory tests with different blending rati...

The specimens of silty sand, standard sand and clay with different void ratios are prepared. By utilizing a multifunctional permeability test apparatus, a series of permeability tests are carried out under the conditions...

The revised density method is improved based on analysis of interactions between ground soil, fill and piles in flow sliding. The density of fill outside the center of sliding surface needn’t be revised. The density of...
