Abstract:

The routine monitoring have disadvantages, such as point type, low quality, low robotization, short monitoring distance, small monitoring area and low integration. BOTDR real time, long distance and distributed monitoring technology is used. The feasibility of the mentioned technology is proved.

Key words: bored pile, BORDR, distributed monitoring, progressiveness.
