A hydraulic loading device and method for model testing

Abstract

The invention discloses a water pressure loading device and method for model testing, comprising a water pressure supply device, a water storage device on the upper part of a model body and a hydraulic pressure measuring device; The device is connected and provides water source for the upper water storage device of the model body; the upper water storage device of the model body is a box structure, the bottom of the box structure is a permeable plate, the top is a jack pressure plate, and the interior is equipped with a supporting water guide column supported on the jack Between the pressurizing plate and the permeable plate; a water pressure measuring device is installed on the outlet pipeline of the water storage device on the upper part of the model. It solves the problem of poor sealing of the hydraulic loading device of the traditional model test and the inability to monitor the water pressure of the model body in real time. It can monitor the water pressure of the model in real time, avoiding the need to record the water pressure of the model at different time points in the traditional test; at the same time, it solves the problem of It solves the problem of human error in measuring the water pressure of the model, and provides a reliable guarantee for the accuracy of the final test data.

Description

technical field [0001] The invention relates to a hydraulic loading device and method, in particular to a hydraulic loading device and method capable of monitoring the hydraulic pressure of a model body in real time. Background technique [0002] With the development of my country's economy, science and technology, and the rapid development of transportation, the development and utilization of underground space has increasingly reflected huge economic and social benefits. The development and utilization of underground space in my country is developing in a modern and scientific direction. With the continuous increase in the number and scale of underground projects, many scholars are studying the optimization of underground engineering design and construction methods in various ways, and exploring the mechanical laws of the construction process. Among them, model test is one of the effective methods to study the law of underground engineering construction process. [0003] T...
