This paper deals with the results of the continuous measurement of the behavior of C. I. P. concrete piles placed in the sliding slope for four years at K-section in Kobe group of the tertiary system.
The results obtained were as follows:
1) Delayed with rainfall, the groundwater level changed in a minute range in the lower part of the slope. There was no relation between the G. W. L. and rainfall.
2) No relation between the change of stress of piles in a line, strain of the intermediate pile, earth pressure, pore water pressure at the measuring point and the change of the G. W. L. was recognized.
3) Difference in the behavior of a pile owing to small difference in the condition of φ and C was small.
4) Bending moment came to a maximum value near the fixed point and the distribution of it showed a damping wave over plus and minus territories.
5) Safety factors of piles to the bending moment and to the shearing force showed large values which were more than Fs=1.2.
6) The results of the continuous measurement for four years showed that no piles was destroyed.
