本文利用勒夫数将日、月作用于地球的引潮力位计算到潮汐形变引起的水平应力,以此作为原地标定的已知应力,用应变固体潮观测资料进行调和分析计算出面积应变的耦合系数及差应变的耦合系数,利用这些系数和仪器钢简的弹性常数计算出围岩的等效弹性常数。最后导出了求解围岩等效弹性常数的实用公式,并计算了两种钻孔应变仪所在的两个台站钻孔的围岩的等效弹性常数,其结果与实际情况基本相符。
In this paper, we calculate the horizontal stress caused by tidal deformation by the tide-force forces acting on the Earth by the Löw number, and use it as the known stress for the calibration in situ. By using the observed data of strained solid tide, we can calculate the area strain Coupling coefficient and differential strain of the coupling coefficient, the use of these instruments and the elastic modulus of the steel to calculate the equivalent elastic constants surrounding rock. Finally, a practical formula for solving the equivalent elastic constants of surrounding rock is deduced. The equivalent elastic constants of the surrounding rock of the two stations where the two kinds of drilling strain gauges are located are calculated. The results are in good agreement with the actual conditions.
