Detecting the underground displacement by integrated sensor equipped with three-dimensional measurement method

Measurement of underground displacement is of great significance. Now, there are various measuring methods to detect underground displacement. But each of them has its own scope of application and limitation. According to actual demand, this paper puts forward an integrated sensor which utilize three-dimensional measurement method to supervise the underground displacement. This sensor can not only measure the size and direction of the displacement, but also can achieve real-time measurement data. Method and realization of displacement measurement are introduced, as well as the experimental data. Comparing with other several measurement methods, three-dimensional measurement method is much better than the normal ones, including high data transmission speed, high sensitivity, strong practicability etc.
