Field measurements and monitoring for prevention of the labour accident by the slope failure under construction

摘要

Sudden failures of slope during or just after slope excavation works cause many serious accidents which sometimes take the lives of workers. Loss of lives and property damages could be prevented if early predictions of failure could be made. In this paper, some measurement apparatus was installed at the slope cutting site, and the installation performance of measurement apparatus, accuracy of measuring; long-term stability, etc. were checked. Although there is no special problem during construction phase, tilt-sensors installed near the slope cutting area showed a little deformation during slope cutting work. In addition, it is found that the slope creeps with some rainfalls event.
