material is one of the basic works of rockburst prediction. After decades of research, based on the laboratory tests, many researchers have put forward a variety of rockburst proneness criteria of rock..., which can be regarded as an inherent material property of rock materials [41, 42, 60-63]. According to the linear energy storage law, there is a strong linear relationship between the elastic energy......
, after the soil stabilization has been carried out, the soil becomes more workable material, more readily manipulated for the construction activities such as loading, leveling, and others. In addition... of this material to determine the water content of the soil specimen. Each 6 kg was wetted with a predetermined percentage of water i.e. 2%, 4%, 6%, 8% and 10% before mixing to the point of obtaining......
; , , is the shear wave velocity of the j-th soil layer; ρj, Gj and Ds,j are density, shear modulus and material damping of the j-th soil layer, respectively; ω is circular frequency and . 2.2.2...-pile system is discretized into two layers, namely, pile and pile end soil. The bottom of the pile end soil is base rock which can be assumed to be rigid. Parameters used here are as follows: length......
the construction of the highway in mountainous area characterized by rocks and soil, the rock filling embankment is the major style. However, the key issue of the rock filling embankment is the quality... of the compactness. However, the accuracies of the above methods cannot meet the requirement of engineering if the filling material is rock. According to the practice of engineering, a laboratory......
