Many of measures to prevent slope failure on construction field are targeted for long-term measurements and sometimes it is unsuitable for use in small-scale construction, therefore we need more easily measurement method.The slope failure monitoring method can grasp the sign of sediment collapse by a simple method and prevent the occurrence of accidents in advance.We installed equipment on the slope slope at the time of construction and verified whether it is possible to predict the deformation.As a result, it was confirmed that the time history at the time of slope collapse due to rainfall was confirmed, and it was confirmed that this system is effective for on-site management.
