Ultra-long pile foundation combined loading test system and method
The invention relates to an ultra-long pile foundation combined loading test system and method, and the system can realize combined loading of various loads of an ultra-long pile foundation, including a vertical static/dynamic load, a horizontal static/dynamic load and a horizontal simulation wave load. Meanwhile, the curved surface application form of real wave acting force to the super-long pile foundation can be simulated, related servo motors are controlled to load in different load forms through programming of an upper computer, and wave cyclic load is applied to a pile body by simulating wave load in combination with a roller clamping sleeve; the physical model provided by the invention can be used for researching the stress deformation condition and the instability failure mode of the super-long pile foundation under the combined action of various loads, so that the physical model test is high in controllability, good in repeatability and high in test efficiency, and can be used for testing the super-long pile foundation under the combined action of various loads. A special test can be carried out aiming at a specific research target, the influence of irrelevant factors is avoided, and the method is a recognized test means with the highest engineering value.
本发明涉及一种超长桩基础联合加载试验系统及方法，该系统可实现对超长桩基础多种荷载的联合加载，包括竖向静/动荷载，水平静/动荷载，水平模拟波浪荷载。同时，可以实现模拟真实波浪作用力对超长桩基础的曲面施加形式，通过上位机编程控制相关伺服电动机进行不同荷载形式的加载，并结合滚轮夹套模拟波浪荷载对桩身施加波浪循环荷载，并通关传感器将数据反馈至上位机进行存储和处理，本发明提供的物理模型，可以开展超长桩基础在多种荷载联合作用下的受力变形情况与失稳破坏模式研究，因此该物理模型试验因可控性高、可重复性好、试验效率高，可针对具体的研究目标进行专项试验，避免无关因素的影响，是公认的最具工程价值的试验手段。
