High-stress bidirectional combined three-dimensional loading device
The invention belongs to the technical field of offshore wind power engineering pile foundation model tests, and discloses a high-stress two-way combined three-dimensional loading device which comprises a model box, a vertical consolidation system is installed on the outer side of the model box, a three-dimensional loading platform is installed on the upper side of the interior of the vertical consolidation system, a vertical loading system is installed on the three-dimensional loading platform, and a three-dimensional loading system is installed on the three-dimensional loading platform. And a horizontal loading system is mounted at the bottom of the three-dimensional loading platform. The pile foundation (structure)-soil interaction under the action of bidirectional load and cyclic load can be simulated, the defect that in-situ stress cannot be reproduced in a common scale model test is overcome, all-directional multi-degree-of-freedom loading positioning of the loading structure is achieved, and the advantages of being high in simulation precision, wide in application range, economical, efficient and the like are achieved.
本发明属于海上风电工程桩基模型试验技术领域，本发明公开了一种高应力双向联合三维加载装置，包括模型箱，模型箱的外侧安装有垂直固结系统，垂直固结系统的内部上侧安装有三维加载平台，三维加载平台上安装有垂直加载系统，三维加载平台的底部安装有水平加载系统。可模拟双向荷载及循环荷载作用下的桩基础(结构物)‑土相互作用，本发明弥补普通缩尺模型试验无法复现原位应力的缺陷，并实现对加载结构物的全方位多自由度的加载定位，模拟精度高，适用范围广、经济高效等优势。
