文章分析了京津唐地区1971年到1976年间98口井的分类及水位变化规律;结合理论推证,提出了计算潜层水活动的重力效应的方法;计算了绝对与相对重力测量可能受到的不同影响;并对唐山地震前的实测重力数据进行了改正计算。
This paper analyzes the classification of 98 wells in Jing-Jin-Tang area from 1971 to 1976 and the water level variation. Based on the theoretical analysis, a method to calculate the gravity effect of the water activity in the sub-horizon is proposed. The calculation of absolute and relative gravity measurements Different influence; and corrected the gravity data before Tangshan earthquake.
