Multifunctional assembly type physical similarity testing system for geotechnical engineering

Abstract

The invention relates to a multifunctional assembly type physical similarity testing system for geotechnical engineering. The multifunctional assembly type physical similarity testing system is characterized by comprising a model box, a loading device and a data acquisition unit, wherein the model box comprises a left side plate, a right side plate, a front side plate, a rear side plate and a bottom plate which are detachably assembled; the loading device comprises a test rack, a sensor, a jack and a control panel, the jack can be glidingly arranged on the test rack in horizontal transverse direction and / or horizontal longitudinal direction and located above the model box, the sensor is arranged above the jack, and the control panel is connected with the jack and the sensor and controls and records data information of the jack and the sensor; the loading device is arranged above the model box; the data acquisition unit is used for acquiring and recording data information of a geotechnical engineering simulation model in the model box. The multifunctional assembly type physical similarity testing system has the advantages that pertinence and accuracy during testing are improved, the rate of utilization of the testing system is increased, and the system can be applied to simulation testing of geotechnical engineering issues such as a slope, excavation of a foundation pit, a pile foundation, a composite foundation, soil anchoring and the like.

Description

Technical field [0001] The invention belongs to the technical field of geotechnical engineering, and specifically relates to a multifunctional assembled geotechnical engineering physical similarity test system. Background technique [0002] In recent years, with my country's rapid economic development and heavy investment in infrastructure, my country has entered a new stage of large-scale infrastructure construction and development. With the continuous development of the field of geotechnical engineering, many geotechnical engineering issues involving abundant groundwater, complex geological conditions, and complex construction environment have emerged one after another. However, foundation pit engineering and slope engineering have also experienced deep, large-scale and complex construction. new trend. According to statistics, at the beginning of the 1990s, the deepest foundation pit in my country was about 20m. At present, the depth of domestic deep foundation pits is usually...

AI Technical Summary

Problems solved by technology

If the model box is too small, it will inevitably bring boundary effects and affect the accuracy of the test results; if the model box is too large, more simulation materials need to be filled, wasting materials and manpower

Most of the traditional model boxes are individually designed according to a certain problem, and the experimental research on other geotechnical engineering problems cannot be completed. After use, the use value is not high, resulting in waste

In addition, the side walls and the bottom plate of the traditional model box are fixed together and cannot be disassembled, which causes certain difficulties in excavation, and takes up a lot of laboratory space when it is idle, and cannot be properly placed

In addition, the traditional model box usually can only solve a certain type of problem, the application range is relatively single, and the utilization rate is not high
