摘要
无论是过去还是现在开展的地震勘探活动,可控震源在工业区或人口密集区作业所面临的巨大挑战都来自于工农关系的处理,特别是如何在地震勘探作业中尽可能地降低对周围环境与建筑物的伤害或将伤害减少到可以掌控的水平,最大可能地降低工农关系处理的复杂性。目前,普遍采用通过测量近源质点爆速(PPV)激发源的安全距离进行约束,但依然存在隐患。本文提出了这样一种可能,通过研究可控震源在激发过程中近源质点爆速(PPV)与大地弹黏参数(GS/GV)的关联性,完善安全评价方法,对可能导致的危害风险提前做出预测,防患于未然。
Whether the seismic activities in the past or in the current, the great challenge is coming from dealing with local relationship, specially to avoid the hazards to nearby facilities or buildings and make Sure those was controllable to reduce complex if it need to deal with. Currently, measuring the near source particle detonation velocity （PPV）, this is the method most commonly employed to determine a safe distance, but there still exists hidden trouble. The paper proposed a method to predict the hazards by analysis the relationship between PPV and Gv iscocity/Gstiffness.
