Description
Technical Field
The invention relates to an experimental device for monitoring the whole disaster-causing process of unstability of a dispersion accumulating dam, which is mainly used for experimental research of the damage process of a tailing dam or a homogeneous earth dam and the disaster-causing process of dam-break debris flow (flood), and belongs to the technical field of geotechnical engineering.
Background
Currently, studies on dam break problems can be divided into two major aspects: (1) Dam break debris flow (flood) evolves in downstream gully; (2) the dam itself damages the breaking process. Related research results and practical engineering experience show that the effective dam bursting early warning mechanism and disaster prevention and reduction scheme can obviously reduce casualties and property loss. On the other hand, the rapid and accurate prediction dam-break debris flow (flood) evolution process can provide important reference basis for the establishment and implementation of disaster prevention and reduction schemes. However, the existing achievements focus on the research of a dam-break mud-rock flow (flood) evolution model and a calculation method, neglect the inherent continuity of a dam-break damage process and a dam-break mud-rock flow (flood) disaster-causing process, and have a certain difference from an actual dam-break disaster-causing process.
Flood flooding, dam foundation destabilization, piping and earthquake are main causes of dam damage. Under laboratory conditions, the dam body damage problem is researched generally according to a model similarity principle, so that more experimental devices aiming at flood and seismic damage are provided, and less dam piping damage experiment researches are provided; the simulation of the dam break mud-rock flow (flood) evolution problem is usually carried out in a groove, slurry with a certain concentration is prepared in advance, the slurry is stored and separated from the end of the groove by a gate, the slurry is released by controlling the gate, the mud-rock flow (flood) formed by instantaneous dam break is simulated, and compared with the dam break process of gradual damage, the simulation result is larger. From dam damage to dam break mud-rock flow (flood) formation is a continuous disaster-causing process, and the current experimental research generally leads the independent study of two process fracture to be different from the actual dam break process, and the defects and the need for improvement still exist. In addition, although dam-break geotechnical experiments under the condition of large scale can completely simulate dam body damage and dam-break debris flow (flood) disaster-causing processes in the dam-break process, the dam-break geotechnical experiments under the condition of large scale are trivial in engineering operation in the process of restoring the dam body and original topography, so that manpower and material resources are huge, and a large number of repeated experiments are difficult to perform to ensure the high efficiency of the experiments. Therefore, the continuity, the integrity and the high efficiency of the emphasized dam break experimental device have important application significance.
