Method for measuring reservoir storage capacity of underground water-seal cave depot

Abstract

The invention provides a method for measuring the reservoir storage capacity of an underground water-seal cave depot. The method includes the following steps that an underground water-seal cave depot measurement control network is established; after the measurement control network is established, measuring parameters of the cross section of the underground water-seal cave depot are defined and the underground water-seal cave depot is scanned; after the scanned data are managed, three-dimensional data of the underground water-seal cave depot are finally obtained; three-dimensional modeling forming is conducted on the three-dimensional data of the underground water-seal cave depot, namely, a plurality of adjacent triangulation networks are established, so that a solid model is constructed and sectioned according to the defined axis vertical direction to form the cross section with the corresponding height; the area of the cross section multiplied by a corresponding and equal height value is computed to obtain the volume of the cross section, the total reservoir storage capacity of the underground water-seal cave depot is obtained according to the total height of the measured underground water-seal cave depot, and the precise volume of the reservoir storage capacity of the underground water-seal cave depot is obtained through adjustment of measured point location precision and measured point location density of the cross section of the underground water-seal cave depot.

Description

technical field [0001] The invention relates to the field of storage capacity measurement of caverns, in particular to a storage capacity measurement method of underground water-sealed caverns. Background technique [0002] In today's society, accurate measurement of the volume of underground karst caves or caverns is a technical problem that needs to be solved urgently. Although the current 3D scanning technology has made great achievements in the acquisition of three-dimensional coordinates of object outlines, due to the large span of caverns and high The side walls and irregular rock walls all bring great technical difficulties to the measurement volume, and it is difficult to realize the collection of larger cavern volumes. Due to the harsh scanning conditions, even if the corresponding volume is measured, the corresponding volume is not accurate, and the error is very large. Large, and the equipment is expensive, and there are certain limitations in its wide application...

[0002] In today's society, accurate measurement of the volume of underground karst caves or caverns is a technical problem that needs to be solved urgently. Although the current 3D scanning technology has made great achievements in the acquisition of three-dimensional coordinates of object outlines, due to the large span of caverns and high The side walls and irregular rock walls all bring great technical difficulties to the measurement volume, and it is difficult to realize the collection of larger cavern volumes. Due to the harsh scanning conditions, even if the corresponding volume is measured, the corresponding volume is not accurate, and the error is very large. Large, and the price of equipment is relatively expensive, and there are still certain limitations in its wide application

For the measurement of the capacity of the cavern, there is currently no high-tech product used to realize the corresponding cavernous measurement means
