The invention relates to an earthquake-proof foundation structure. The earthquake-proof foundation structure comprises a first raft, a second raft, shock absorption plates, and liquid storage wells, wherein the bottom of the first raft protrudes downwards to form a plurality of evenly-distributed round piers; a groove matched with the round piers is formed in the top surface of the second raft, and the groove bottom of the groove is in elastic fit with the bottoms of the round piers to form a shock absorption barrier in the vertical direction; the shock absorption plates are fixed to the two side surfaces of the first raft and the two side surfaces of the second raft correspondingly, a shock absorption cavity is formed inside each shock absorption plate, calcium carbonate is placed at thebottom of each shock absorption cavity, and slurry inlet holes are formed in the positions, 300-400 mm away from the top surface of the first raft, of the tops of the shock absorption cavities; and the side wall of the top of each shock absorption plate is provided with one liquid storage well communicating with the corresponding slurry inlet hole, dilute hydrochloric acid is stored inside the liquid storage wells, and under the action of earthquake horizontal force, the dilute hydrochloric acid enters the shock absorption cavities through the slurry inlet holes to react with the calcium carbonate to generate CO2 gas to form a shock absorption barrier in the horizontal direction. Earthquake vibration energy is reduced and consumed in the horizontal direction and the vertical direction, theshock absorption effect is good, the structure is compact, and the input cost is low.
本发明涉及一种防震基础结构，包括：第一筏板，第一筏板底部向下凸出有多个均匀分布的圆墩；第二筏板，第二筏板顶面上形成有与圆墩配合的凹槽、且凹槽槽底与圆墩底部之间为弹性配合形成竖直方向上的减震屏障；减震板，第一筏板和第二筏板两侧面均固定有减震板，每一个减震板内部均形成减震腔，减震腔底部放置有碳酸钙，其顶部距离第一筏板顶面标高300‑400mm处设置有入浆孔；以及储液井，每一个减震板顶部侧壁均设有与入浆孔连通的储液井，储液井内储存有稀盐酸，在地震水平力作用下，稀盐酸经入浆孔进入减震腔与碳酸钙反应生成的CO2气体形成水平方向上的减震屏障。实现了在水平方向和竖直方向减小和消耗地震震动能量，减震效果好，结构紧凑，投入成本低。
