地すべりの自動観測システムにおける2, 3の問題

抄録

We used integer as a record format, therefore the number of records could be fivefold. Many softwares enabled us to record the deformation of underground continuously under many conditions. The result of pipe-strain meter needed to be checked by an insertion type of strain meter. It is pointed that observer should make sometimes visits of inspection to observation machines in operation and that he should ex amine the sensitivity of extensometer and groundwater-meter. A few weak points, for example problems of thunder prevention, the way of ground and so on, are noted.
