Model Test Study of Squeezed Branch Pile under Horizontal Vibration Load

Abstract

Based on the self-design model experimental system of dynamic soil-pile dynamic interaction, strong horizontal dynamic load was exerted to two models of squeezed branch pile, and the bearing plate location of the two squeezed branch piles is different. The model experiment adopt digital frequency converter to control the loading frequency, and use spring of different stiffness coefficient to achieve different load level. In order to analyze the action of bending moment and the status of lateral earth pressure changes, different sizes of excitation frequency and excitation load were setted during the test.
