密封措施对降低洞体形变观测气象类因素干扰的效果与分析

摘要

结合2010年5月初的一次密封措施，以天为单位统计各月内影响淮北地震台洞体形变观测的气象因素类型及其变化情况，分析造成干扰的主要气象因素类型及密封效果，结果表明：影响淮北台洞体形变观测的主要气象类型为大风、气压和降水，密封能有效降低大风和气压因素造成的干扰。%Combining the hermetic solution in early May 2010, this paper statistics the meteorological factors types and their changes per month by days, and analyzes the types of main meteorological factors causing disturbance and the hermetic solution effect. The results show that:the strong wind, air pressure and rainfall are the main factors that effect observation data, and the disturbance of air pressure and strong wind on observation data was reduced after taking the hermetic solution.
