摘要
对桃花吐跨断层短水准不同观测方法资料的对比分析结果表明,流动水准测量成果能代表该点某一时段的高差动态变化状态,但资料的动态精度较低.认为除了复测周期外,测量方法的简单和测线过长也是造成流动水准测量成果预测预报地震效果不佳的主要原因之一.本文还对提高效果的途径提出了见解.
Comparing with the data gained from defferent observation methods of leveling over fault at a site Tao huatu and analysing them have been made in this paper.The results show that.the observations of mobile leveling can represents the dynamic variation of level inerement at the site, but the dynamic precision of the data is lower. We think the simplification of surveying method and the long surveying line are major reasons making low effect of farecasting earthquake by mobile leveling besides the resurveying period .In this paper, we have also shown an opinion to increase effect of earthquake predition.
