Test model for simulating relationship between immersion depth of bridge pier and bearing capacity of bridge pier

Abstract

The invention provides a test model for simulating the relationship between the immersion depth of a bridge pier and the bearing capacity of the bridge pier. The test model comprises test area clamping plates, two extension area water tanks and a bridge pier model; a pier bottom clapboard is fixedly connected between the surfaces of the two test area clamping plates; a river bed simulation area isarranged among the lower surface of the pier bottom clapboard and the inner bottom walls of the test area clamping plates; and the river bed simulation area is filled with river bed sediment. The invention relates to the field of bridge construction. When the test model for simulating the relationship between the immersion depth of the bridge pier and the bearing capacity of the bridge pier is used, interference of the river bed sediment can be reduced; a relatively large amount of sediment is not required; on the contrary, the sediment holding power authenticity can be improved; material consumption is reduced; furthermore, the volume of the model can be reduced; and therefore, the following problems are effectively solved: when the general bridge pier test model is used, a bridge pier bearing and shaking critical point is not convenient to grab; the test effect is not easy to observe; the model used for simulating the river bed sediment is relatively large; and use is inconvenient.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a test model for simulating the relationship between the draft depth of a bridge pier and the load-bearing capacity of the pier. Background technique [0002] With the development of science and technology, in the construction industry, especially for some relatively large-scale construction projects, in order to ensure the accuracy of construction projects and reduce engineering losses caused by engineering errors, relevant models will be built to simulate during the construction process. During the construction of the bridge pier, it is necessary to determine the heavy capacity of the pier according to factors such as the depth of the river bed, draft and water flow, and then match the appropriate bridge and pier. After the burial depth of the river bed is determined, measure the weight of the pier according to the water level and water velocity Stability, if it is ...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a test model for simulating the relationship between pier draft and pier load-bearing capacity, which solves the problem that the general pier test model is inconvenient to grasp the critical point of pier load-bearing and swaying when it is used. The effect is not easy to observe, and the model used for simulating riverbed sediment is large in size and inconvenient to use
