Dynamic property and breaking soil mechanism of water jet

摘要: 水射流破土效果取決于射流參數和土體參數,射流參數決定射流作用力的大小,而土體參數決定著土體臨界破壞力．通過射流動力特性及其破土機理分析,揭示了射流參數與土體參數之間存在的內在聯系,建立了水射流破土的理論方程．該方程解決了以往在射流破土過程中參數選取的隨意性或無法確定射流參數的問題．Abstract: Water jet breaking soil effect is determined by water jet parameters and soil parameters. Water jet parameters decide the water jet impact force, while soil parameters do the soil critical destructive force. Based on analyzing the dynamic property and breaking soil mechanism of water jet, the internal relationship between water jet parameters and soil parameters was discovered and the theoretical equation of water jet breaking soil was established. This equation solves the problem hard to precisely select parameters during the process of water jet breaking soil.
