Abstract

The invention relates to a simulation platform, an experiment system and a method for reservoir leakage detection experiments, and the platform comprises a sand box, and the upper part of the sand boxis provided with an opening so as to expose an inner cavity of the sand box. An earthing layer is laid on the upper surface of the bottom wall of the sand box. A simulated dam body is arranged at oneend of the sand box, the simulated dam body is supported by a soil covering layer, a water storage tank is defined by the side face, close to an inner cavity of the sand box, of the simulated dam body and the inner wall of the sand box, and the relative position of the simulated dam body and the sand box can be adjusted to change the size of the water storage tank. The water storage tank can be filled with experimental water so as to simulate water resources stored in a reservoir. A drainage device is arranged on the bottom wall of the sand box so as to drain accumulated water leaked from thesoil covering layer.

Description

technical field [0001] The disclosure belongs to the technical field of water conservancy engineering reservoir leakage detection, and in particular relates to a simulation platform, an experimental system and a method for a reservoir leakage detection experiment. Background technique [0002] At present, with the rapid development of my country's economy, the contradiction between supply and demand of water resources has become increasingly acute, and the construction of reservoirs has become the main means to solve the contradiction between supply and demand of water resources. It is backward, and there are different degrees of leakage problems after completion, and the complexity and risk of reservoir leakage problems are relatively high, so it is essential to carry out leakage detection work on reservoir leakage problems. [0003] The inventor understands that the problem of reservoir leakage is a ubiquitous and seriously harmful problem in water conservancy projects. How...
