Problems solved by technology

The advantage of the centrifugal model test is that the stress field of the prototype can be reproduced with a smaller model. The disadvantage is the size effect of the soil particles. In addition, due to the small size of the model, it is difficult to select, arr...

Embodiment Construction

[0019] As shown in Fig. 1 and Fig. 2, the present invention comprises the rectangular steel structure model groove that main body steel structure beam column 1 and main structure side steel plate 2 are formed, and the inner bottom surface of this groove and four inner side surfaces all take sealing measures, so that in No water leakage or air leakage during use; the inner wall of the side steel plates 2 of the main structure is specially smoothed to reduce side friction and boundary effects; Each row has a plurality of instrument embedding holes 3 and data lead-out wire holes 4, to facilitate the monitoring instrument embedding and the drawing of instrument signal lines; A side visible window 5, through which the lateral displacement of the soil during the test can be observed and measured, special sealing measures are taken around the visible window; gravel and sand pads at the bottom of the rectangular steel structure model tank Layer 16 is provided with multiple rows of bra...

Abstract

The invention relates to a testing platform with ground and slope engineering module. Long edge at one side of the main structure side steel plate has an instrument burying hole and data leading out hole, the other side having viewing window, bottom of the rectangular structural module slot rubble and sand cushion having water pipe supply net that connects with the water tank and vacuum extraction device, one side of the short edge of the main body structural side steel plate having discharge hole, two sides of the main structural beam post overpass the latched the reverse beam, whose lower end having hydraulic jack, ball hinges and bearing plate formed servo bearing system, displacement sensor, sand pressure sensor and gap water pressure connected to form the monitoring system. It can be deployed to prevent disasters.

Description

technical field [0001] The invention relates to a model test device used in the technical field of geotechnical engineering, in particular to a model test platform suitable for foundation and slope engineering. Background technique [0002] my country is a country where mountains and hills are widely distributed. Various slopes are often encountered during civil engineering construction, including natural slopes, excavated slopes and filled slopes. These slopes may be unstable and slide under various natural or man-made disaster conditions (such as heavy rain, rising water level, excavation, stacking, etc.), causing casualties and property losses. Due to the complex and diverse hazard-causing factors of the slope, its instability mode and catastrophe mechanism are very complicated. In order to deeply understand the mechanism of slope disasters under complex environmental conditions, correctly evaluate the stability of slopes, and propose economical and effective disaster pr...
