Sandbag cofferdam applies flexible load on soil foundation. The failure mode and sliding surface of soft soil foundation under sandbag cofferdam should be significantly different from that under rigid base. Aimed to get ...

Calcareous sand is a special kind of geotechnical sand which consists of much carbonate. Based on the remains of the original marine organisms, the calcareous sand grains have irregular shapes and contain inner pores. Th...

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 dynamic shear modulus and damping ratio are the two main parameters for describing the dynamic characteristics of soil. The tests on the saturated sand under isotropically consolidation by TSH-100 resonant column app...

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...

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...

A liner system containing clay or bentonite-sand mixtures is installed on the bottom of a landfill to prevent contaminants from flowing into the surrounding ground. The influence of Ca2+ concentration and local settlemen...

In the available researches on the cyclic resistance ratio (CRR) of saturated sand-gravel mixtures, the factors such as gravel content, sample preparation method, relative density and consolidation stress ratio have been...

There is local shallow and strong permeable stratum in dike (dam) foundation, and its head dissipating capacity is weak. It is easy to cause piping failure, and the failure mechanism still needs further studies. The eros...

The vibration-induced liquefaction in soils is a notable hottopic in geotechnical engineering. The building collapse and embankment burst induced by liquefaction are fatal for the loss of lives and properties of human be...

Through numerical simulation based on the particle flow method, DEM numerical test samples are generated in accordance with the results of laboratory tests on standard sand. Using gravity deposition modelling of irregula...

A series of undrained cyclic triaxial tests are conducted under various types of artificial irregular loadings to investigate the combined effect of loading amplitude and sequence on the pore pressure characteristics of ...

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...

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...

"El presente informe tiene como principal objetivo analizar la viabilidad económica de desarrollar el recurso de Tight Gas Sands en la Argentina. Para ello, en primer lugar, se analiza la situación macroeconómica de ...

Tesis de Maestría La presente investigación está destinada a examinar el desarrollo institucional y socioeconómico del Banco Español del Río de la Plata y reconstruir principalmente la trayectoria de los miembros d...

In order to overcome the deficiency of the existing double-ring infiltrometer (DRI) for the soils with high permeability, a new DRI is developed. The device is composed of water injection system and water supply system. ...

There is not a consistent conclusion on the influences of loading frequency on dynamic modulus and damping ratio, and the quantitative results are few. Through a series of tests using the new cyclic triaxial (CT) divice ...

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...

Field case studies after earthquake show that pile foundation can be severely damaged by bedrock fault movement. The failure mechanism of this type of foundation damage is not yet fully understood. Centrifuge modeling of...

In Puerto Iguazú City, Argentina, human and canine Visceral Leishmaniasis cases have been recorded since theyear 2010, with Leishmania infantum as the etiological agent and Lutzomyia longipalpis as its main vector. In t...

By using the limit analysis upper bound theorem, the elastic solution of dynamic Brazilian tests is optimized. Considering the effects of the radially angled cracks caused by the high-speed impact at contact points of th...

Comparison self-synthesized dental porcelain between feldspar from Pangaribuan and Sukabumi. Dental porcelain material as one of the esthetic indirect restorations in Indonesia is mostly imported. In fact, Indonesia is ...
