This study presents an experimental and theoretical investigation of the coefficient of earth pressure at rest K 0 in tetrahydrofuran hydrate-bearing sands. Hydrate crystals creep, and thus, measured K 0 values manifest time-dependent behavior. The coefficient K 0 in hydrate-bearing sediments is ...

At rest earth pressureAngularitySurface roughnessDiscrete element methodClumped particleThe at-rest earth pressure coefficient, [equation], is one of the most fundamental values for evaluating in-situ soil stresses and designing foundation. Research has been expanded to investigate the......
In the case of vertical stopes, the value of K has sometimes been defined using the at-rest earth pressure coefficient K0, while others have applied Rankine's active earth pressure coefficient Ka. To help clarify this confusing situation, which can lead to significantly different results, the ...
Explain the concept of "earth pressure" in retaining wall design. How do engineers calculate earth pressure and use it to determine the stability and design of retaining walls for various soil conditions?There are 3 steps to solve this one. Soluti...
The static earth pressure coefficient of soils is, approximately, considered to be a constant in the view of classical soil mechanics. This is supported by many research results. The high pressure experimental research and analysis of remolding deep soil described herein indicate that the static ear...
The magnitude of earth pressure coefficient in calculating the earth pressure on bridge abutment depends significantly on the degree of restraint provided by the abutment. For example, active earth pressure is usually adopted for cantilever abutment because there is possible occurrence of small relieving...

In terms of gender, women’s happiness is significantly higher than men’s (b = 0.118, se = 0.027), probably due to the fact that Chinese men generally bear more work pressure and family expectations, or there may be significant psychological differences between genders. The coefficient of ...
