Any object on the earth is subject to gravity as a result of the gravitational attraction and the centrifugal force caused by the earth’s rotation. Scientists perceive the gravitational field as the normal gravitational field (1g≈9.8 m/s2) and define the condition where the force of gravity exceeds that on the surface of the earth (greater than 1 g) as hypergravity.Apparently, in the context of ...

    High-speed rail is cited by news media as one of China's "four great inventions" in modern times. While China witnesses a quick expansion of the high-speed rail network, much attention has been drawn to the issue of safety. Among others, the vibration caused by a running train may lead to shock waves and generate the Mach effect, thereby affecting its safety and co...

Steel-concrete composite structures are made of steel and concrete material or composted of steel and concrete sub-structures. Steel-concrete composite structures are widely used in engineering structures due to the satisfying utilization of the two materials of steel and concrete. With the development of technology, new kinds of composite structures and elements are constantly emerging which requ...

    The annual urban solid waste in China, which is mainly domestic waste, reaches 240 million tons, ranking the first in the world. Landfill accounts for 90.5 % of the total disposal of urban solid waste in China. The landfill site in China is as high as 100 meters with a capacity of tens of millions of cubic meters.
