One-time continuous loading device capable of being used for centrifuge anchoring base

Abstract

The invention discloses a one-time continuous loading device capable of being used for a centrifuge anchoring base. The one-time continuous loading device comprises a mold box, and a set of force applying system, wherein the two sides of the mold box are provided with transparent organic glass, the edge sides of the mold box are provided with grooves capable of fixing fixed pulleys, and the set offorce applying system is composed of a guiding rail, a force transferring plate, a hydraulic press and a steel strand and can achieve simultaneous loading of the two sides of the mold box; and a plurality of axial force sensors are arranged at the bottom of the force transferring plate, and a camera capable of recording the experimental process in the box is arranged outside the mold box. According to the one-time continuous loading device, the space utilization rate in the box can be significantly increased, the positions of the fixed pulleys in the grooves can be adjusted to change the loaddirection so as to simulate bearing mechanisms of the anchoring base under different working conditions, the fixed pulleys for transferring force are fixed into the grooves, the steel strand is attached to the inner wall surface of the mold box, the situation that the force transferring steel strand cannot be completely attached to the inner wall of the mold box, and consequently the load direction offset error is generated is avoided, the precision and accuracy of an experiment are improved, and the one-time continuous loading device has the great potential and prospects in the geothermal centrifugation experiment.

Description

Background technique [0001] Geotechnical engineering has been developed as a formal discipline for more than half a century. However, due to the complexity of geotechnical materials, this discipline is still a semi-empirical discipline. In recent years, due to the development of the constitutive relationship of rock and soil and numerical analysis technology, the more accurate quantitative research on geotechnical engineering has made a big step forward, thus improving the reliability of the prediction of engineering properties. However, the accuracy of this analysis technique first depends on the degree of understanding and simulation of rock and soil properties, and the degree of simplification of boundary conditions, and secondly depends on the conditions of mathematical calculation techniques, so there are still many imperfections. At the same time, the above-mentioned analysis techniques still lack the verification of necessary experiments and field data. For this reaso...
