Non-Newtonian fluid variable stiffness energy dissipation and seismic mitigation anchor rod and construction method
The invention discloses a non-Newtonian fluid variable-stiffness energy dissipation and shock absorption anchor rod and a construction method, belongs to the field of rock-soil retaining engineering and vibration control, and particularly relates to an active variable-stiffness energy dissipation and shock absorption anchor rod technology. The structure of the non-Newtonian fluid variable-stiffness energy dissipation and shock absorption anchor rod is composed of a variable-stiffness device 1 and an anchor rod 18, and the variable-stiffness device 1 is composed of a fixing cover 2, a variable-stiffness spring 8, a connecting piece 12, a piston 15 and a connecting shaft 16; the anchor rod is composed of a free section and an anchoring section. And the anchor rod 18 is connected with the variable stiffness device 1 through a thread 17 to form the integral non-Newtonian fluid variable stiffness energy dissipation and shock absorption anchor rod. The variable stiffness device connected to the anchor head can automatically increase the spring stiffness when an earthquake occurs, the relative displacement of a vibration area and a stable area is reduced, and the stability of a supported area is improved. The construction method comprises the following steps: (1) surveying and designing; (2) drilling; (3) constructing an anchor rod 18; (5) assembling the non-Newtonian fluid variable stiffness energy dissipation and shock absorption anchor rod; and (6) the site is restored, and construction is completed.
