Horizontal and vertical combined loading device and method for pile foundation model test
The invention discloses a horizontal and vertical combined loading device and method for a pile foundation model test. The horizontal and vertical combined loading device comprises a model box groove formed by welding angle steel and steel plates. The model pile is pre-buried in a soil body in the model box; the side surface of the model box is used for horizontally loading the device A; the upper part of the model box is used for vertically loading a device B; the positions of the horizontal loading pulley and the combined pulley used for vertical loading are adjusted respectively, weights are placed on the corresponding loading components according to test requirements, and the loading test of horizontal, vertical or combined loads of the model pile is achieved. According to the invention, horizontal and vertical loading of the model pile ground can be realized at the same time, when the pile top generates horizontal or vertical displacement, the change of vertical and horizontal loads can be very small and can be ignored, and the bearing character of the pile foundation under the combined load effect can be better analyzed.
本发明公开了一种桩基模型试验用水平与竖向组合加载装置及方法，包括由角钢和钢板焊接的模型箱槽；预埋在模型箱内土体中的模型桩；模型箱侧面用于水平加载装置A；模型箱上部用于竖向加载装置B；分别调整水平加载滑轮和用于竖向加载的组合滑轮的位置，根据试验要求在相应的装载构件上放置砝码，实现对模型桩的水平、竖向或组合荷载的加载试验。本发明可以同时实现对模型桩地水平和竖向加载，桩顶在发生水平或竖向位移时，能够实现竖向和水平荷载的变化很小可以忽略，可更好地分析桩基在组合荷载作用下的承载性状。
