Abstract(in English) It is doing the road protection against disasters the inspection and the check work of the dangerous part. However, at the wide area, the number of the parts, too, is, taking time because it is many. Also, the danger accompanies for the steep landform. It developed a measurement system to attempt to make reduction of labour, for the safety to improve. It uses a optical fiber for the sensor and it measures the change of the rock and so on. It confirmed the efficiency of the optical fiber sensor by the indoors examination, the virtual field examination which used imitation equipment. Also, it did a proof field in the actual scene. The measurement precision is bad compared with the electric formula sensor. However, it was possible to confirm that it had constant efficiency as the means of watching over the change of the rock and so on. It is possible to watch, being remote because it is using a optical fiber.
