摘 要: 提出了一种连续、精密测量地壳岩体两点间水平距离相对变化的新电测法,通过阻值传感换能系统,运用专门的热屏设计和电磁屏蔽,使得该法适用于有电磁场和高湿环境等恶劣条件下的工作。 A new electrical method for measuring continuously and accurately the strain in the rockregion near a hydropower staion dam is proposed.With a specific resistance-sensing systemand specially designed thermal screens and electromagnetic shields,the method is suitablefor use in poor environmental conditions,such as under the influence of a strong magneticfield and high moisture.
