Abstract

The invention discloses an experiment device for simulating dam overtopping of a tailing dam under a rainfall action and an experiment method and belongs to the technical field of theories and experiments of the dam overtopping of the tailing dam under the rainfall action. By combining two aspects including a theoretical technology and a testing technology, a dam overtopping mechanism of the tailing dam is jointly disclosed. The experiment device comprises a water circulating and hydrostatic load applying system, a simulated rainfall system, a levelness control system and a simulated reservoir area system; when the simulated reservoir area system is used for simulating rainfall under a real field condition, a dam body attribute replacement body need to be replaced with a real material. By combining a differential hydrostatic pressure theory based on a water-crossing section shape and a similar experiment for simulating real rainfall conditions, the experiment device has the advantages of water saving and environment protection, low cost, convenience and flexibility in dynamic and static load application, flexibility of replacing the dam body attributes, high controllability and the like.

Description

technical field [0001] The invention belongs to the theoretical and experimental technical field of tailings dam flooding under rainfall, and discloses a tailings dam flooding simulation experiment device and an experimental method under rainfall. Background technique [0002] A large number of tailings dam failure mechanisms show that tailings dams, as a man-made debris flow hazard source with high potential energy, have different degrees of safety hazards whether they are closed, abandoned or in operation. Macroscopically grasp the causes of many tailings dam failures, whether it is seepage, scour, flooding or liquefaction, etc., are all related to water factors. Although flooding is not the most frequent and major form of damage, the negative impact of the tailings dam failure caused by flooding is unprecedented. There are direct data. On August 25, 1985, the Niujiaolong tailings pond of Hunan Shizhuyuan Nonferrous Mine collapsed and the direct economic loss of the minin...
