试验表明,振动时土壤强度比静态低,并具有和静态不同的破坏机理。土方工程机械由地面提供牵引力并以土壤为作业对象。因此,研究振动时的土壤特性,合理地利用振动技术来提高机械的作业效率,必然导致生产费用的降低,有现实的经济意义。本文综述了国内外在这一领域的研究成果。
Experiments show that the soil strength under vibration is lower than the static state and has a different failure mechanism from the static state. Earthmoving machinery is provided by the ground with traction and soil as the object of work. Therefore, studying the soil characteristics during vibration and using the vibration technology rationally to improve the working efficiency of the machine will inevitably lead to the reduction of the production cost, which has realistic economic significance. This article summarizes the research results at home and abroad in this field.
