Abstract

The invention discloses a method and a device for dynamically measuring the evolution process of a dam break, belonging to the field of dynamic measuring dam break devices. A method and device for dynamically measuring the evolution process of a dam break. In order to effectively solve the problem of size effect in small-scale dam-break tests and the problems of hard-to-find, time-consuming, high-cost and high-risk sites for large-scale dam-break tests, the device is designed The dam break centrifugal model test mechanism enables it to simulate the dam break process of a 100m high dam, thus providing an advanced means for studying the break mechanism of the tailings pond and its influencing factors, and accurately measuring the dam break flow process; the past dam break The test is basically a water tank test, and the camera has been used to record the dam break process, but this method has no way to quantitatively record the development of the break in the dam break process, such as the width and depth of the break at a certain moment. The new test box proposed by the present invention can solve this problem.

Description

technical field [0001] The invention relates to the field of dynamic measuring dam break devices, in particular to a method and a device for dynamically measuring the evolution process of a dam break. Background technique [0002] Dam break, that is, the dam collapses. It is one of the important topics in the design and management of hydraulic projects, and it is a disastrous flow phenomenon. Therefore, it is necessary to study the process and mechanism of dam failure. However, due to the small size of the previous test models, the model and The stress level of the prototype is too different. For the tailings pond whose strength and deformation characteristics are significantly related to the stress level, it is debatable whether the test results can reasonably reflect the failure mechanism and process of the tailings pond. With the support of relevant state departments, the applicant's research team conducted in-depth research on the method and device for dynamically measu...
