Problems solved by technology

Its disadvantages are: (1) The test loading device and test model are huge, the requirements for the site are high, and the test cost is very high; (2) The test method is single, and the applied load is mainly designed for sediment flow, which cannot simulate the impact of uniform fluid pressure on the support. The impact of t

Abstract

The invention discloses a retaining structure impact load simulation test device and method. The device comprises a test stand, a loading container and an impact mechanism, a steel wire rope is pulledto slide on a pulley through a weight which is a free falling body, a force transfer strip is pulled to drive a retaining plate to quickly slide upwards along a sliding rail to open the loading container, small steel balls in the loading container quickly gush, lateral impact load is simulated through the small steel balls to impact a retaining structure, and impact force of the small steel ballsto a test model can be changed by adjusting capacity and height of the loading container or a distance between a fixing plate and the loading container. The defect that original retaining structure member impact texts are large in occupied space, unitary and inconvenient for teaching application is overcome, and the device has the advantages of being simple in structure, uniform in impact stress,reusable, small in occupied area, suitable for various different models, capable of simulating impact tests of various fluid pressures, high in adaptability and suitable for being applied in scientific research teaching tests, and the method is simple and applicable.

Description

technical field [0001] The invention belongs to the technical field of strength testing of civil engineering support structures, and relates to a support structure impact load simulation test device and a test method. Background technique [0002] Retaining structures (such as retaining dams, retaining walls, cofferdams, etc.) that mainly bear lateral pressure are widely used in civil engineering and have various structural types. In addition to conventional static loads, this type of structure often also bears lateral impact loads. It is necessary to investigate the mechanical characteristics and failure characteristics of retaining structures under lateral impact forces through structural model tests. The existing model test research plan is to build an inclined plane impact test bench, use the kinetic energy generated by one or several large-diameter steel balls rolling down the chute to simulate the impact of large solids on the retaining structure, or design solid-liqui...
