A civil engineering anti-seismic structure includes a base. A fixing structure is fixedly welded at the bottom center of the base. A through-hole is provided at the top center of the base. Sliding grooves are provided on corresponding inner walls at two sides of the base. Sliding blocks are slidably connected to the sliding grooves inside the grooves and are symmetrically installed at two sides of a sliding plate. A top block is fixedly welded at the top center of the sliding plate (8), and a fixing groove is provided at the top center of the top block. A shock-absorbing damping pad is fixedly adhered to a bottom inner wall of the base. A first limiting plate is fixedly welded around the top portion of the sliding plate, and a second limiting plate is fixedly welded around the through-hole at a top inner wall of the base. 1.
