[0002] In the traditional design scheme, the final anti-slip force design value of the tank is calculated based on the deadweight of the tank body and the ground-supported platform and the sliding friction coefficient of the actual rock foundation. The tank structure can only meet the design requirements when the calculated anti-slip force is greater than the horizontal seismic force.
[0003] To achieve this goal, the thickness of the foundation needs to be increased to increase its own weight, thereby improving the anti-slip force. This approach will significantly increase the material and construction costs. At the same time, thickening the cushion layer requires rock excavation, which increases the construction difficulty and construction period.

[0010] Furthermore, an inclined hole is opened in the foundation rock layer so that the thrust anchor rod can be inserted and set in the inclined hole.
[0011] Furthermore, the thrust anchor comprises a first thrust anchor and a second thrust anchor, one end of the first thrust anchor and the second thrust anchor are respectively connected to the steel mesh, and the first thrust anchor and the second thrust anchor are inserted into the inclined hole at one end away from the steel mesh.
[0012] Furthermore, the first thrust anchor rod and the second thrust anchor rod are symmetrically connected to the steel mesh frame, and the first thrust anchor rod and the second thrust anchor rod are arranged close to one end connected to the steel mesh frame.
[0013] Furthermore, the thrust anchor also includes a third thrust anchor and a fourth thrust anchor, one end of the third thrust anchor and the fourth thrust anchor are respectively connected to the steel mesh, and the third thrust anchor and the fourth thrust anchor are inserted into the inclined hole at one end away from the steel mesh.
[0014] Furthermore, the third thrust anchor rod and the fourth thrust anchor rod are symmetrically connected to the steel mesh frame, and the third thrust anchor rod and the fourth thrust anchor rod are arranged close to one end connected to the steel mesh frame.
