Vertical support column bearing capacity test simulation device in reverse construction environment
The invention provides a vertical support column bearing capacity test simulation device in reverse construction environment. The device comprises a box body, a steel tube test piece, bedrock, an actual pile, soil layers, a pressure applying assembly, a control unit, and a test unit, wherein the bedrock whose middle part is provided with a pile hole is placed into the box body, the steel tube testpiece filled with concrete is coaxially inserted into the actual pile arranged in the pile hole, a plurality of layers of soil layers are compacted in sequence above the bedrock in the height direction of the box body, a medium material can fill the space between the inner side wall of the soil layer and the surface of the steel tube test piece, the pressure applying assembly is used for applyingpressure to the upper end of the steel tube test piece, and the control unit is in signal connection with a plurality of strain gauges and a plurality of displacement meters D arranged on the steel tube test piece and connected with the controlled end of the pressure applying assembly. According to the device, a pile is the actual pile, and a steel tube filled with the concrete is used as a column. According to the device, the influence, generated when different gaps are adopted between the pile and the column for backfill materials, on the constraint effect of the support column is researched through the test, so as to verify the rationality of the vertical support column slenderness ratio calculation formula.
一种逆作法施工环境下竖向支撑柱承载能力试验模拟装置，包括箱体、钢管试件、基岩、实际桩、土层、施压组件、控制单元、测试单元，中部开设有桩孔的基岩放置到箱体内，内部填充有混凝土的钢管试件同轴插在桩孔内设置的实际桩中，在基岩的上方，多层土层沿箱体的高度方向上依次夯实设置，所述土层内侧壁和钢管试件表面之间可填充介质材料，所述施压组件用于给钢管试件上端部施压，所述控制单元与设置在钢管试件上的多个应变片和位移计D信号连接，并与施压组件的受控端连接。该发明桩为实际桩，填充有混凝土的钢管作为柱，本申请通过试验研究桩柱之间采用不同空隙回填材料对支承柱的约束作用影响，作为验证竖向支承柱长细比计算公式的合理性。
