BEHAVIOR OF BORED PILE FOUNDATION ON SLOPING GROUND UNDER LATERAL LOADING

Abstract

The northern region of Thailand has a plateau landscape and a risk of earthquake. Buildings may be constructed on the sloping ground and a question about the strength of pile for resisting earthquake is asked many times from residents. The objectives of this research are to study the behavior of bored pile subjected to lateral loading by doing experiment, the details of bored pile are from the construction drawing of staff dormitory building at University of Phayao where islocated on the area of sloping ground, and to compare the experimental results with the analysis of pile model with lateral spring which is taken into account lateral soil pressure. The results of this study show that the pile constructed on the sloping ground can resist the lateral load effectively. In addition, the analysis of pile with lateral spring that usually done by engineers can capture the behavior of pile subjected to lateral loading in the conservative way although the pile is on the sloping ground.
