The vibration isolation support for installing the static force level gauge is an adjustable passive vibration isolation support, the static force level gauge is placed on the vibration isolation support, the liquid level oscillation phenomenon caused by environment pulsation and vehicle excitation can be effectively eliminated, the accuracy of bridge safety monitoring is enhanced, and the safety of a bridge is improved. High-reliability analysis data is provided for subsequent bridge operation state evaluation, the health condition of the bridge is truly reflected, unnecessary maintenance cost is reduced, and the maintenance cost of the whole life cycle of the bridge can be effectively reduced. The bridge deflection monitoring device solves the problem that the monitoring accuracy is affected by liquid level oscillation in a communicating pipe of a static force level gauge when the bridge deflection is monitored by the static force level gauge in the prior art.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a vibration isolation support used for installing a static level and a design method thereof. Background technique [0002] Deflection is an important parameter for bridge safety monitoring and evaluation. In order to know whether there is any abnormal deformation of the bridge structure, it is necessary to perform multi-point synchronous dynamic monitoring of the deflection. [0003] The measurement methods for bridge deflection include inclinometer method, high-speed photography method, total station method, GPS observation method, static leveling observation method, etc. Among them, the static level has the characteristics of multi-measuring point synchronous detection, high precision, wide application range, less environmental interference, and high cost performance. [0004] It is generally believed that the response of the liquid medium lags behind the bridg...
