The large-diameter ultra-long piles are commonly adopted for constructing ocean platform foundations. The pile-sliding phenomenon frequently takes place because of the great weight of both the piles and the hammer. Engin...

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...

The design criteria of Terzaghi filter layer have laid the foundation for the researches on filter layers, which are safet enough for uniform cohesionless soil, but not secure for uneven cohesionless soil, and they are n...

In order to study disaster evolutionary process and failure characteristics of Yonglian tunnel of Ji'an-Lianhua highway under the effect of disturbance, taking F2 fault fracture zone as the research object, a large-scale...

Needle-punched GCL and HDPE geomembrane (GM) are widely used in impermeable engineering, and the whole shear strength of multi-layer composite liner with GCL is crucial for the slope stability. A large simple-shear testi...

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...

The actual engineering problems induced by super low-strength soft clay are paid more and more attention with the rapid development of port and ocean engineering. However, the routine geotechnical experimental method can...

The dewatering effect of dredger fill using the vacuum preloading incorporated with electro-osmosis in different ways is evaluated by implementing six laboratory tests. The test results show that the asynchronous consoli...

As the water pressure of shield tunnel increases, the key to tunnel construction is to strengthen the water resistance of joints. By analyzing the characteristics of stress and deformation of the gaskets in the joints of...

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...

As a building material, the loess is usually required to be compacted in engineering construction, thus the deformation characteristics of compacted loess with the increase of water content are closely related to the saf...

Based on the actual state of the soil along rail transit in hot and rainy area, the resonant column tests on the soil under wetting and drying circles are conducted to study the stiffness characteristics of residual soil...

The impact roller (IR) compaction method is an efficient and cost-effective compaction technique, which has been widely used in highway and airport engineering for subgrade compaction and ground improvement of soft found...

Soft clay is influenced by the time-dependence of viscosity and consolidation as well as coupling effect of moisture. In order to study the effect of moisture content on soft clay foundation, by introducing the elastic-v...

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...

Currently the application of 50 drill pipe is more in the standard penetration test (SPT) in the geotechnical engineering investigation, which is different from the code that 42 drill pipe is specified. Based on the proj...

Pore structure is the index reflecting the nature of the physical and mechanical properties of the soil. The resolution scale of the traditional medical CT is not high enough to identify the single grain or pore characte...

The tests are performed to study the gas permeability of unsaturated intact Q3 loess with various water contents under different isotropic stresses using the improved triaxial gas permeability equipment. The influences o...

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...

Geothermal energy pile is the new pile technology that combines the ground source heat pump technology and building pile foundation. Due to the pile as the heat transfer carrier of ground source heat pumps, the bearing c...

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...
