通过观察，分析模型试验的现象和结果，讨论了爆炸加密饱和砂的机理，研究了药量与地表下沉量的规律，指出在爆炸加密砂基的问题中比药量不是主要的物理参数。总结出了地表下沉量及爆炸作用范围的计算公式。研究结果表明，爆炸振动引起砂体的破坏与再排列是砂基密实的主要原因。
Through observing and analyzing the phenomena and results of model tests, the mechanism of explosion-encrypted saturated sand was discussed, and the law of dose and surface subsidence was studied. It was pointed out that the specific drug quantity was not the main physical parameter in the problem of explosion-engraved sand base. Sum up the calculation formula of surface subsidence and explosion range. The results of the study indicate that the destruction and rearrangement of sand bodies caused by explosion vibration are the main reasons for the compaction of sand bases.
