Description

A kind of plate apparatus and method for simulating side load
Technical field
The present invention relates to field of civil engineering, more particularly to a kind of plate device for simulating side load and side Method.
Background technology
Plane-plate loading test is to be classified to be further applied load on the rigid bearing plate of certain size, is observed under load actions at different levels The home position testing method that foundation soil deforms with pressure.This method experiment is relatively more directly perceived, simple, is widely used for many years;But its It is no more than twice of bearing plate width (or diameter) in the presence of the influence depth scope of experiment, shallow layer foundation soil characteristics can only be reflected Shortcoming, therefore to embedded depth of foundation larger high level or high-rise building, plate be typically after excavation of foundation pit on earth after Cheat what bottom was carried out.But the shortcomings that side produced by can not considering embedded depth of foundation periphery foundation soil carries is still suffered from, experiment gained ground Base bearing capacity is relatively actual serious relatively low, can not often meet requirement of engineering.To solve the problem, deep layer is used sometimes in engineering Plate, but deep plate load testing presence need to carry out test well excavation supporting, precipitation, with high costs, experiment week The prominent shortcoming such as phase length, therefore only applied in some especially important construction projects.
The content of the invention
The present invention provides a kind of plate apparatus and method for simulating side load, can solve institute in background technology The problem of pointing out.
A kind of plate device for simulating side load, including several device for exerting, the device also include first Bearing plate and the second bearing plate that can be nested in inside first bearing plate, a device for exerting are arranged on described the The center of two bearing plates, remaining device for exerting are arranged on first bearing plate and on the center week of second bearing plate To being uniformly distributed, first bearing plate is the annular of annular or pros;
When first bearing plate is annular, second bearing plate is circle, first bearing plate it is outer straight Footpath is four times of the diameter of second bearing plate;
When annular of first bearing plate for pros, second bearing plate is square, first bearing plate Four times of the length of side of a length of second bearing plate in outside.
More preferably, the device for exerting is five, and a device for exerting is arranged on the center of second bearing plate, Remaining four described device for exerting is arranged on first bearing plate and circumferentially uniform on the center of second bearing plate Distribution.
More preferably, the device for exerting is jack.
A kind of plate method for simulating side load, including:
S1, the second bearing plate is nested in the first bearing plate, and is positioned over foundation surface to be tested;
S2, a jack is arranged into the center of the second bearing plate, by four jack in the second bearing plate The heart is evenly arranged on the first bearing plate, makes that it is equally loaded;
S3, the pressure value for pressurizeing and maintaining four jack thereon step by step to the first bearing plate are certain value, the definite value Payload values inverse obtains as produced by foundation soil in the range of practical basis buried depth;
S4, observe the situation that foundation soil deforms with pressure under load actions at different levels.
The present invention provides a kind of plate apparatus and method for simulating side load, breaches for high-rise or superelevation The limitation of layer construction foundation bearing capacity evaluation mid-deep strata plate, using outside nested bearing plate and the method for voltage stabilizing Load produced by foundation soil, can obtain the foundation bearing capacity being more consistent with virtual condition in the range of analog basis buried depth, This method equipment simple processing, simple to operate, experimental period is short, cost is relatively low.
