淹没射流破土分析与模拟的ALE 方法和实验的对比

摘要

For the study of the mechanism and ground conditions of submerged jets, it compares the hole shape and hole depth with the use of numerical simulation of ALE method and experimental simulation.The results show that the shape and depth of the hole by ALE method are consistent to experimental results, and the hole de-velops into the linear change, which is the same as fact.The analysis of ALE method based on submerged jets break soil is actually feasible.%为研究淹没射流破土的机理和条件，从冲坑形态、冲坑深度等方面进行ALE方法数值模拟和实验模拟。结果表明，ALE方法得出的冲坑形态与冲坑深度和实验结果基本一致，且冲坑发展呈线性变化，与实际情况相同，说明采用ALE方法描述淹没射流破土分析是可行的。
