Testing device for simulating pile foundation
The invention provides a test device for simulating a pile foundation, and relates to the field of civil engineering, and the test device comprises a model box filled with a soil body; at least part of the bearing pile model is buried in the soil body; the lateral deformation simulation system is arranged in the model box and located on at least one side of the soil body, and the lateral deformation simulation system can make at least part of the soil body displace; the detection device is fixed to the surface of the bearing pile model and used for obtaining stress and deformation of the bearing pile model. The loading and unloading process is flexibly simulated through the lateral deformation simulation system, the lateral loading and unloading state of foundation soil adjacent to the pile foundation is restored, stress and deformation data of the existing pile foundation in the disturbance mode are obtained, and the bearing state response rule of the existing pile foundation is obtained.
本发明提供一种模拟桩基的试验装置，涉及土木工程领域，该试验装置包括模型箱，装有土体；承载桩模型，至少部分承载桩模型埋设于土体之中；侧向变形模拟系统，设置于模型箱内，且位于土体的至少一侧，侧向变形模拟系统可以使至少部分土体发生位移；检测装置，固定于承载桩模型的表面，用于获取承载桩模型的受力和形变。通过侧向变形模拟系统灵活模拟加卸载过程，还原桩基邻近地基土侧向加卸载状态，获取扰动模式下的既有桩基的受力和形变的数据，得到既有桩基承载状态响应规律。
