Abstract

The invention belongs to the technical field of earthquake engineering simulation research, and discloses a dam body shock test simulation device with controllable vibration frequency zoning. The simulation device mainly comprises a data acquisition system, a vibration table module, a foundation box, a foundation and a dam body, wherein the vibration table module comprises a high-frequency vibration table and a low-frequency vibration table; the dam body receives transmitted low-frequency and high-frequency synthesized vibration; a water tank communicated with the foundation box in a flexiblesealing manner is fixedly arranged on the low-frequency vibration table; the dam body divides communicated zones into upstream and downstream water body zones; the upstream water body zone is arrangedon one side of the water tank; upstream water in the upstream water body zone receives low-frequency vibration; the low-frequency vibration acts on the dam body; and a damping boundary body is arranged between the foundation box and the foundation. The device adopts high- and low-frequency vibration zoning simulation, so that dam body shock test simulation more meets an actual use condition of alarge-scale high dam; obtained test data tends to be reasonable and accurate; and the test cost is lowered.

Description

technical field

[0001] The invention belongs to the technical field of earthquake engineering simulation research, and relates to a dam body seismic test simulation device with controllable vibration frequency divisions. Background technique

[0002] In recent years, in order to adapt to the rapid development of my country's hydropower industry, a large number of high-dam water body areas have been built or started to be built. At present, among the top 100 dam heights in the world, my country accounts for 20, of which 14 are over 200m. It is not uncommon for water conservancy dams with dam heights over 300m to be found in my country. As my country's geographical structure runs through many earthquake zones, the seismic performance of dams is a very important assessment index in the design and construction of projects. It is related to the safety of dams, as well as the safety of life and property of downstream cities and population, especially High dam project. Therefore, ...
