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...

Water build-up has continued to be one of the leading causes of performance variability and loss of durability in proton exchange membrane fuel cells (PEMFCs), especially at the high current density and transient operati...

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...

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 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...

With the further development of marine exploration in China in recent years, higher requirements are put forward for the capacity of the soil and cyclic loading effect for the offshore engineering. Due to the difficulty ...

In response to the threats posed by underwater explosions to the stability of island-reef engineering structures and coral reef ecosystems, this study investigates the dynamic response characteristics and carbon emission...

ObjectiveLimestone water hazards in coal seam floors represent one of the two primary categories of mine water hazards in China. Limestone aquifers are generally characterized by abundant static water reserves and consid...

Surface water recycling is essential for addressing water scarcity in arid regions like Iran. This study assesses the feasibility of enhancing surface water reuse in Tehran’s urban infrastructure by focusing on the cit...

Transformer is a vital equipment in the power system. If the transformer is damage, can cause the electrical distribution to the consumer will be disrupted. Therefore, it needs special maintenance the performance of the ...

Based on one - dimensional leaky model for base aquitard of deep excavations, analytical solutions for the excess pore water pressure induced by variation of artesian water head and the corresponding exit gradients in th...

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 ...

A series of undrained cyclic tests with variable confining pressures are conducted on Ningbo saturated soft clay by using the GDS cyclic triaxial system. In this study, the coupling effects of cyclic deviatoric stress an...

Abstract At present, the water-cooling simulation of the water-cooled magnetic coupler is based on the water-cooled motor and the hydraulic coupler, which cannot accurately characterize the temperature distribution of th...

This study investigates the fragmentation expansion and water storage characteristics of collapsed rock in overlying strata during its formation. Pre-static loaded fractured samples of four typical roof rock types-coarse...

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...

According to the landslide characteristics of the slope of the reservoir bank of Longjiang Hydropower Station in Yunnan Province, laboratory tests are conducted to investigate the characteristics of the landslide under t...

Humanity currently lives in a technological era that witnesses rapid progress in multiple fields. Digital image processing is one of the modern technologies that has provided practical answers to many challenges includin...

Abstract Water-based lubrication is an effective method to achieve superlubricity, which implies a friction coefficient in the order of 10−3 or lower. Recent numerical, analytical, and experimental studies confirm that...
