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 necessity to reduce the weight of transport structures, such as cars and airplanes, has become more important due to gas emission regulations. In this regard, the use of hybrid structures made of steel and aluminum i...

According to deformable coordination condition, the sliding soil mass will deform to adapt to the curve of logarithmic spiral which will lead to energy dissipation. To quantify this energy dissipation, two multi-blocks p...

Using the ring shear apparatus, the variation rules of residual strength of 17 saturated claysoil samples with different plasticity indices under different consolidation conditions are studied. The influences of current ...

Jacking force is one of the crucial parameters to decide design of pipe structure, selection of pipe jacking meachines and design of shaft structure for jacking projects. In order to more accurately calculate the jacking...

The large-diameter monopiles of offshore wind turbines are always subjected to multiaxial loads. The design criteria for the vertical and lateral bearing behaviors of piles are designed independently, while lots of tests...

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...

Soil acidity is one of the reasons for corrosion of steel piles. The material deterioration of steel pile foundation served in the acidic soil will affect the safety and durability of pile foundation. In order to underst...

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 CU triaxial tests and ring shear tests on interface between steel pipe pile and soil of a kind of intact marine soft clay with medium structure are carried out under influence of shear strain rate, and the variations...

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...

To illustrate the variation laws of strength characteristics and micromechanism of rubber-sand mixtures, a series of laboratory tests including direct shear tests, unconfined compressive strength tests and scanning elect...

In the loess regions loess landslide is one of the major geological disasters. Every year it results in a large number of casualties and destructions. It is found that the average shear stress on the sliding surface of t...

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...

The deep excavation has a significant influence on the bearing capacity and settlement of piles beneath excavation. However, there are few researches on the influencing factors, especially the distribution of strata. In ...

In order to study the influence of the backfill characteristics of the large karst area on the load transfer of the pile foundation and to improve the safety and economy, considering the characteristics of the side frict...

Based on the ellipsoid theory of particle flows, that is, an ellipse sliding face is presented in the loosening zone at upper part of tunnels, a method is deduced to calculate the lateral earth pressure coefficient relat...

The settlement control of the high-speed railway subgrade plays an important role in comfortable and safe running of high-speed train. With the growth of operation time, the long-term settlement of railway in soft subgra...

The influence of chemo-mechanical activation of dispersed carbon fibers in their turbostrate and quasicrystalline structure in terms of modeling frictional contact has been researched. It has been shown that change of pa...

This paper presents shakedown analysis of a half-space obeying Von-Mises criterion under Hertz loads in plane strain model. Based on the static shakedown theorem, a rigorous shakedown solution is established by searching...

A series of CU triaxial tests on clay reinforced by basalt fiber are performed under controlled soil dry density conditions, and the ratio of basalt fiber content to dry soil by weight is 0.0%, 0.1%, 0.2%, 0.3% and 0.4%....
