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

Embodiment 1

[0079] The multifunctional assembled geotechnical engineering physical similarity test system includes a model box, a loading device and a data acquisition device. The model box includes a left side panel, a right side panel, a front side panel, a rear side panel and a bottom panel; the left side panel , The right side plate, the front side plate, the rear side plate and the bottom plate can be detachably assembled into a box. The loading device includes a test frame, a sensor, a jack and a control panel. The upper part of the test frame can be slidably connected to the jack, that is, the jack can be along Horizontally and horizontally and / or horizontally and vertically slidingly arranged on the test frame and above the model box; the sensor includes a displacement sensor and a tension sensor, the displacement sensor is arranged on the jack, the tension pressure sensor is arranged above the jack, and the control panel is connected to the Control and record the data information o...

Embodiment 2

[0089] On the basis of Example 1, when the model box is in use, the model box can be properly heightened according to the needs of the test, such as Figure 5 As shown, the raised front side panel 401, the raised rear side panel 501, the raised left side panel 601, and the raised right side panel 701 are adopted. The lower edges of the four raised side panels correspond to the front, rear, left, and There are through holes at the upper end of the right side plate, and corresponding through holes are provided on the side edges of the adjacent heightening side plate. The connection between the heightening rear side plate 501 and the rear side plate 5 can be adopted by connecting the heightening rear side plate 501 and the rear side. The plate 5 is partially overlapped, and the through holes are fixed by bolts; steel strips with corresponding through holes on the upper and lower ends can also be used, and the rear side plate and the rear side plate are respectively fixed with the th...

Embodiment 3

[0094] When using the multi-functional assembled geotechnical engineering physical similarity test system of Example 1 for test simulation, the model box should be assembled first, and the left and right side panels, front and rear side panels of the model box should be fixed to the bottom plate by bolts according to the position. On the upper side, the side plates are bolted with L-shaped steel, and steel strips are added on the opposite side of the L-shaped steel to prevent stress concentration at the bolts.

[0095] When laying the experimental research substrate, if the research substrate is a soil layer, it can be divided into two situations: When the soil layer is sandy soil, the sand rain method can be used for laying, and the porosity of the soil body should be checked every time it reaches a certain height to ensure The uniformity of the soil layer; every certain height, a certain thickness of colored sand is evenly spread on the side close to the side plate where the ima...

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...
