摘要

海洋环境中的导管架平台承受着风浪、地震等水平荷载，而平台的稳定对桩基础有严格要求，故研究水平荷载下导管架平台桩-土系统变形规律和相互作用机制具有重要意义。研制了1套导管架平台桩-土相互作用试验系统，主要由导管架平台试验模型子系统、电动伺服加载子系统、传感器与数据采集子系统、振动测试子系统组成，可用于研究冲击荷载、静载、循环荷载下导管架平台的桩身变形规律、桩基周围土体响应及平台的振动特性。通过初步试验结果表明，该系统能够如实反映水平荷载下桩-土间的相互作用和导管架平台的振动特性，验证了该系统的有效性。

Abstract

Jacket platform suffers the wind

waves

earthquake and other lateral loads; while the stability of platform has strict requirements for pile foundations. Therefore

studies of the behavior and deformation mechanism of pile foundation under lateral loads are of great significance. A new test system has been developed to simulate the response of pile foundations subjected to lateral loads. The system consists of a jacket platform test model subsystem

an electric servo loading subsystem

a sensor and data acquisition subsystem

and a vibration test subsystem. It can be used to study the deformation mechanism of pile foundations

the response of soil around pile foundations and the vibration characteristics of jacket platform subjected to lateral impact

static and cyclic loads. The test results show that the system can simulate pile-soil interaction and vibration characteristics of jacket platform effectively.
