钻孔耦合对体应变观测的影响分析
Effect of coupling on the borehole strain observation
摘要
Abstract
In this paper,based on the combined model of three thick wall cylinders,the mutual con-version formula between different types of borehole strain is given.The effect of model pa-rameters on three types of borehole strain observation is analyzed.Through analysis of the strain data on more than 60 stations,it is found that there is no simple correspondence be-tween barometric coefficient and tidal factor on the same station.By earth tide,the strain of different boreholes is calibrated into the unified system strain.The results indicated that many strain tidal factor observation were significantly smaller than the theoretical value. Therefore,that may be related to borehole incompletely coupling.关键词
