FULL-SCALE MODEL TEST FOR EARTHQUAKE RESISTANT REINFORCEMENT METHOD FOR PILE FOUNDATIONS BASED ON GROUND SOLIDIFICATION TECHNIQUES

Abstract

The earthquake resistant reinforcement method for pile foundations is limited by various unfavorable construction conditions. The authors proposed a new method for earthquake resistant reinforcement applicable to either new or existing pile foundations, which was confirmed model shaking table test under 1g gravitational field and the numerical simulation analysis. A full-scale model test of the proposed method was conducted to examine the construction performance and the quality of reinforcement body in the pile foundation. The full-scale test includes lateral loading tests, vibration tests and excavation of the reinforcement body for observation. Based on the test results, applicability of the proposed reinforcement method for a real pile foundation was confirmed.
