Abstract: This research is monitoring the ground condition inside the aging slope. The purpose of this research is to consider the value of a monitoring method with the ground evaluating system to estimate the soundness in the aging slope. In Japan, at the high economic growth period after the 1960’s, a great number of slopes were formed to construct many roads and most slope protection methods were to cover with shotcrete on the slope. Now, those slopes are aging. Therefore, there is a possibility that the slope failures occur due to the weather and natural disaster such as climate variations, heavy rainfall and earthquake. It is important to establish the method monitoring the ground condition inside the slope to estimate the soundness in the aging slope and to effectually maintain slopes. In this research, firstly, by using elastic wave exploration and electric detection, we examined the ground condition in situs. Secondly, we changed each measured results of geophysical explorations into the porosity and the saturation with the ground evaluating system. This system uses seismic velocity – the porosity and the saturation relational expression (Wyllie 1956) and the resistivity – the porosity and the saturation relational expression (Archie 1941).
