This paper deals with the results of the continuous measurement of the behavior of C.I.P. concrete piles placed in the sliding slopes for four years at N-O-section in Kobe group of the tertiary system. The results obtained were as follows : 1) Groundwater level changed in a range of 0.5∿0.7 meters but there was no relation between groundwater level and rainfalls. 2) Stresses and strains of piles in a line, and earth pressures and pore water pressures at the measuring points were found to change in correspondence with slow decline of groundwater level. 3) In the fourth year, stresses of the piles in a line grew larger and some piles changed over plus and minus territories. But no pile was destroyed for four years. 4) Minute changes in strains of the intermediate piles suggested that the present intervals of piles were inappropriate. 5) Differences in the behavior of piles owing to small differences in the condition of φ and C were small. 6) Bending moments came to maximum values and the distributions of them showed damping waves over plus and minus territories. 7) Safety factors of piles to the bending moment showed small values which were less than Fs=1.0. 8) To make safety factors to the bending moments larger, it was necessary to intensify piles by increasing section area, reforming the qualities of piles and increasing reinforcing steels.
