Simulation test equipment and method for super-load anchor pile cross beam counter-force device
The invention discloses simulation test equipment and method for a super-load anchor pile cross beam counter-force device. In the equipment, the middle parts of two secondary beams are arranged on the top faces of the two ends of a main beam, and anchor pile caps are arranged on the top faces of the two ends of the secondary beams; two secondary pressure-bearing counter-force box girders are arranged on a test platform, and counter-force anchor pile caps are arranged on the bottom faces of the two ends of the secondary pressure-bearing counter-force box girders; four main pressure-bearing counter-force box girders are arranged side by side, and the two ends of the four main pressure-bearing counter-force box girders are arranged on the top faces of the middles of the two secondary pressure-bearing counter-force box girders; four-hole box girders are arranged at the two ends of the four main pressure-bearing counter-force box girders in a sleeving mode; an upper steel box cushion and a lower steel box cushion are arranged on the bottom face of the middle of the main beam and the top faces of the middles of the four main pressure-bearing counter-force box beams; six sets of jacks are arranged between the upper steel box cushion and the lower steel box cushion; a plurality of first twisted steel bars are welded between the anchor pile caps and the counter-force anchor pile caps; and a displacement sensor and a dial indicator are arranged on the main beam and the two secondary beams and used for detecting rigidity and deformation. According to the method, the main beam and the four main pressure-bearing counter-force box beams are subjected to graded loading and unloading through six sets of jacks, and whether the main beam and the secondary beams meet the requirement of the maximum load or not is judged.
本发明公开了一种用于超大荷载锚桩横梁反力装置的模拟试验设备及方法，本设备中两根次梁中部设于主梁两端顶面，锚桩帽设于次梁两端顶面；两根次承压反力箱梁设于试验平台，反力锚桩帽设于次承压反力箱梁两端底面，四根主承压反力箱梁平排布置并且两端设于两根次承压反力箱梁中部顶面，四孔箱梁套设于四根主承压反力箱梁两端，上下部钢箱垫设于主梁中部底面和四根主承压反力箱梁中部顶面，六台套千斤顶设于上下部钢箱垫之间，锚桩帽与反力锚桩帽之间焊接若干第一螺纹钢筋，位移传感器和百分表设于主梁和两根次梁用于检测刚度和变形。本方法通过六台套千斤对主梁和四根主承压反力箱梁进行分级加载和卸载，判断主梁和次梁是否满足最大荷载时的要求。
