INSPECTION OF EMBANKMENT SLOPE AGAINST FAILURE BY A SIMPLIFIED PORE-PRESSURE METER

The process of designing a simple apparatus to inspect the disorder of slope by surveying the strength of slope, rising of pore-pressure, change in inclination of slope prior to failure is described. The pore-pressure rises high after each rainfall in a peculiar slope, the surface of which is loose and underlied by hard layer. Such a slope failed at the test embankment by artificial rainfall. The apparatus totalling 86 pieces had been driven into slopes at several places. Two slopes failed actually. These slopes have the typical feature above mentioned. The pore-pressure rose up to the slope surface and the inclination of the meters to their original position was 26 degrees. If a a number of meters are driven into slopes, some of them may work for inspecting the disorder of slopes.
