Visual shear box for pile sinking interface parameters considering interface fluid-solid coupling effect
The invention discloses a visual shear box for pile sinking interface parameters considering the interface fluid-solid coupling effect. The visual shear box comprises an upper shear box body and a lower shear box body, wherein a sliding groove is formed in the surface, connected with the lower shear box body, of the upper shear box body, and a groove is formed in the surface, connected with the upper shear box body, of the lower shear box body; the visual shear box further comprises a concrete pipe pile test piece and an external loading device, wherein the concrete pipe pile test piece comprises a test piece a, the lower end of the test piece a is connected with a test piece b, the test piece b is embedded into the groove, and the test piece a is embedded into the sliding groove; and theexternal loading device comprises an outer frame, a first screw rod and a second screw rod, the upper shear box body and the lower shear box body are located inside the outer frame, a vertical loadingdevice is arranged at the top of the outer frame, and a horizontal loading device is further arranged on the inner wall of the outer frame. The shear box is simple in structure, economical, and convenient to install during testing, the pile-soil interaction characteristic under the fluid-solid coupling condition can be simulated, and the accurate and reasonable pile-soil interface friction coefficient can be obtained.
本发明公开了一种考虑界面流固耦合效应的沉桩界面参数可视化剪切盒，包括上剪切盒和下剪切盒，上剪切盒与下剪切盒连接的表面设置有滑动槽，下剪切盒与上剪切盒连接的表面设置有凹槽；还包括混凝土管桩试件和外部加载装置，混凝土管桩试件包括试件a，试件a下端连接试件b，试件b嵌入凹槽中，试件a嵌入于滑动槽中；外部加载装置，包括外框以及第一螺旋杆和第二螺旋杆，上剪切盒和下剪切盒位于外框内部，外框顶部设置有竖向加载装置，外框内壁还设置有水平加载装置。该剪切盒构造简单、经济，试验时安装方便，可模拟在流固耦合条件下的桩土相互作用特征，能得出较为准确合理的桩土界面摩擦系数。
