The invention provides the measuring system against the problem that the prior art can not effectively measure the internal flow rate of the debris flow, the measuring system comprises a measuring device, a data collection device and a data processing device which are sequentially connected, wherein the measuring device comprises at least one impact sensor and at least one hydrostatic pressure sensor, the force receiving surface of the impact sensor is vertical to the flow direction of the debris flow; the force bearing surface of the hydrostatic pressure sensor is parallel to the flow direction of the debris flow; and the impact sensor and the hydrostatic pressure sensor which are positioned at the same horizontal height are used for measuring the original impact and the hydrostatic pressure of slurry of the debris flow at the horizontal height respectively. The measuring method provided by the invention can calculate according to data obtained by the measuring system, thereby obtaining the internal flow rate of the debris flow. The measuring system has simple structure, the measuring method has reliable principles, easy operation and high accuracy of measurement result, and the measuring system and the measuring method can be used in the flow rate measurement of the debris flow in field prototypes and indoor tests.

Description

technical field [0001] The invention relates to a debris flow velocity measurement system and measurement method, in particular to a measurement system, a measurement method and an application thereof for inversion calculation of debris flow velocity through measurement of debris flow impact force. Background technique [0002] Debris flow is a common natural disaster that is widely distributed in mountainous areas of our country and is relatively serious. Debris flow velocity is one of the core research contents of debris flow mechanics, and is the key to study the rheological properties and movement mechanism of debris flow. It is related to the calculation of important engineering design parameters such as debris flow flow, average velocity, impact force, and motion friction. It has always been an important basic data that debris flow researchers and engineering technicians at home and abroad are eager to obtain. At present, the commonly used measurement methods of debri...
