Structure for connection pile foundation and balancing weight in shaking table test and using method thereof

Abstract

The invention provides a structure for connection a pile foundation and a balancing weight in a shaking table test and a using method thereof. The structure comprises the balancing weight; an embeddedsteel plate is arranged at the bottom of the balancing weight; a horizontal steel plate is arranged below the embedded steel plate; a plurality of embedded bolts which vertically penetrate through the embedded steel plate, the horizontal steel plate and the balancing weight are fixedly connected with the horizontal steel plate; the pile foundation is arranged below the embedded steel plate; the bottom of the horizontal steel plate is vertically and fixedly connected with a vertical steel plate which is located on the side of the pile foundation and matched with the pile foundation in the aspect of shape; a plurality of second bolt holes are formed in the vertical steel plate; fixed bolts which horizontally penetrate through the vertical steel plate and the pile foundation are arranged inthe second bolt holes; and a plurality of first bolt holes which are used for adjusting the size according to the pile foundation are formed in the horizontal steel plate. The structure is simple in structure, reasonable in design and flexible to use, is capable of effectively avoiding waste, can be recycled and has practicability.

Description

technical field [0001] The invention relates to a structure of a shaking table test connecting pile foundation and a counterweight and a method for using the same. Background technique [0002] With the development of my country's road traffic and the increasing number of projects, pile foundations have been used in most projects. However, due to the loss of people, lives and property caused by earthquakes, it is often necessary to conduct research on shaking table experiments. Due to the limited bearing capacity of the shaking table, it is difficult to set the artificial mass for the scale model of a large structure or a model with a large length-to-mode ratio. Switching to a model that ignores gravity severely limits the applicability of the experimental results. Therefore, under the condition of not exceeding the bearing capacity of the shaking table, set as many artificial masses as possible to meet the needs of the experiment. [0003] In shaking table experiments, t...

Problems solved by technology

[0003] In shaking table experiments, traditional pile foundation counterweights (such as Figure 11 shown) is often poured together with the pile foundation according to the required counterweight, and the counterweight is wasted in vain after the experiment

This traditional method not only brought a lot of trouble to the pouring process, but also caused the counterweight to be unusable after the experiment was over, resulting in a serious waste of experimental materials and environmental pollution.
