Pseudo-Dynamic Test Analysis of Rigid Pile Composite Foundation

According to the similarity theory, this paper established a geometric similarity 1:10 and 3 × 3 rigid pile composite foundation pile group model. Pile strain , cushion deformation and flask displacement were obtained through pasting resistance strain gauges in pile, embedding strain gauge in cushion, connecting to displacement sensor at out of flask, etc., basing on pseudo-dynamic test method. These date were analyzed and studied, and then can conclude the response pattern under earthquake action on rigid pile composite foundation, which provide a basis for application of rigid pile composite foundation in practical engineering.
