Problems solved by technology
[0003] Due to the differences in the lithology and soil conditions of the embankment stratum, the diversity and complexity of slope failure factors are difficult to analyze by numerical methods. Therefore, the current experimental methods are not targeted, the test period is long, and the effect is not ideal. For soil and rock The research on the failure mechanism of the dam slope is not clear enough

The invention provides an earth-rock dam slope damage testing device under a seepage condition. The device comprises a vibratory loading table and a model box installed on the vibratory loading table;the slope model box comprises an upstream part, a trapezoidal earth-rock dam model part and a downstream part, all of which are sequentially distributed from left to right; and the vibratory loadingtable comprises a vibratory base, a horizontal vibration device and a vertical compaction loading device, wherein the vibratory base is used for carrying the model box. Through the device, an earth-rock dam slope with multiple slope grades under the seepage condition can be simulated; spatial stress in an arbitrary direction is exerted on the earth-rock dam slope damage testing device under the seepage condition, and the action of loads in an earthquake, construction etc. is simulated; and loading is performed on the earth-rock dam slope repeatedly, a cyclic load is simulated, data generated during damage is recorded, the damage mechanism is studied, and the device has application value in emergency risk removal and consolidation and other work. Therefore, multiple slope stress conditionscan be precisely simulated, an experiment is convenient and efficient, and an experiment result has high precision and high reference.
Description
technical field [0001] The invention relates to the field of slope stability research in geotechnical engineering, in particular to an earth-rock dam slope failure test device and a use method under seepage conditions. Background technique [0002] Due to many external factors such as seepage, earthquake, precipitation and top overload, earth-rock dams are prone to landslides and even dam failure accidents. [0003] Due to the differences in the lithology and soil conditions of the embankment stratum, the diversity and complexity of slope failure factors are difficult to analyze by numerical methods. Therefore, the current experimental methods are not targeted, the test period is long, and the effect is not ideal. For soil and rock The research on the failure mechanism of the dam slope is not clear enough. Contents of the invention [0004] In order to solve the above problems, the present invention proposes an earth-rock dam slope failure test device and a method of use ...
