Changes in earth pressure during the installation of a bored pile are measured using "geo-cells" which have been buried around the piles. Four piles are tested ; two of those are installed by the simultaneous burial method, one by normal pre-boring method and another is driven by a hydraulic hammer. For bored piles, the effective lateral earth pressure at the level of pile tip measured by geo-cells decreases first according the penetration of drilling rod and then turns to increase and records the maximum value when the tip of the rod reaches the geo-cell level. These features are similar to those of driven pile. The residual earth pressure after installation by the simultaneous burial method even keeps larger value than the inherent earth pressure before installation.
