从大地测量技术、地震观测技术和钻孔应变观测技术３种地面运动观测方法在观测频带和观测精度方面的互补性，探讨了钻孔应变观测技术的发展方向。指出钻孔应变观测应将观测重点放在周期数十秒到数十天的短临信息频段，同时指出，钻孔应变观测可以同时用于地声和高频地震观测，以获取更多的短临信息。 Based on the complementarity of three kinds of ground motion observation methods in geodetic survey, seismic observation and borehole strain observation in observation frequency band and observation precision, the development direction of borehole strain observation technique is discussed. It is pointed out that the observation of borehole strain should focus on the short-term information frequency band of several tens of seconds to several tens of days. Meanwhile, the observation of borehole strain can be used for both geoacoustic and high frequency seismic observations to obtain more short Pro information.
