Abstract

The invention discloses a device and method for simulating a three-dimensional animal cave disaster-causing mechanism of a homogeneous embankment, which comprises a centrifugal model box, a supporting mechanism, a drawing adjustment mechanism, a cave simulation frame and a safety detection mechanism. The pulling adjustment mechanism includes a slide rail, a slide block and a horizontal pulling drive device; the cave simulation frame includes a circular ring and at least three straight rods; Form the non-fixed end of the apex and pre-buried in the embankment; by adjusting the angle between each straight rod and the ring, the simulation of different three-dimensional animal caves is realized; the safety detection mechanism includes displacement sensors, osmometers, seepage monitoring sensors and image measurement systems. After the dam model reaches the predetermined centrifugal acceleration, the invention realizes the production simulation of the three-dimensional cave network of termites, badgers and other animals, truly reflects the appearance of animal caves during the operation of the dam, and reveals its disaster-causing process and Disaster mechanism.

Description

technical field [0001] The invention relates to the technical field of hydraulic embankment failure model tests, in particular to a device and method for simulating the disaster-causing mechanism of three-dimensional animal caves in homogeneous embankments. Background technique [0002] The centrifugal model test has the same stress level as the prototype, and has gradually become an important means in the field of dam failure mechanism research. Existing centrifuge model tests of dykes focus on flooding, hydraulic splitting and other aspects. [0003] There are 290,000 km of dikes and 98,000 reservoirs and dams in my country. Although most of the dikes and dams have been built up to the standard or reinforced, due to their large volume and wide area, many dikes and small reservoir dams still have safety hazards such as poor local quality and distribution of animal and plant caves. These potential safety hazards are the weak link in the embankment project and the short boa...
