Dynamic optimization and intelligent regulation and control configuration method for wide-source cementing materials of cemented dam

Abstract

The invention discloses a dynamic optimization and intelligent regulation and control configuration method for a wide-source cementing material of a cemented dam, which comprises the following steps of: firstly, carrying out site selection on a sand gravel yard based on a space-time Kriging interpolation method, carrying out a sampling test, and then determining a mixing ratio control range of the cementing material of the cemented dam according to a sampling test sample; and then comparing the real-time mixing ratio of the cementing material mixed on site with the control range of the mixing ratio of the cementing material, giving an alarm for the cementing material with a relatively large error value, and finally constructing a statistical model of multiple factors on compressive strength by adopting a grey correlation method according to the performance index of the cementing material so as to predict the compressive strength of the cementing dam, and evaluating the mixing quality through the compressive strength of the cemented dam. According to the invention, digital and intelligent regulation and control of the cementing material mixing process are realized, and the problem that in the prior art, the cementing damming material with performance indexes meeting requirements is difficult to prepare by using a local material with high dispersion, wide grading and maximum particle size of 300mm is solved.

Description

technical field [0001] The invention belongs to the technical field of cement mixing control, and in particular relates to the design of a method for dynamic optimization and intelligent regulation and configuration of cemented dam wide-sourced cement. Background technique [0002] Cemented dam is a new cemented dam system other than earth-rock dams and concrete dams. Dam-building materials are widely sourced, including local materials such as natural river bed gravel, bedrock and slope excavation materials, and artificial crushed aggregates. The gradation of aggregate is not unique. Use a small amount of cement, fly ash, admixtures and local materials that are not screened or washed on the project site to cement them into materials with certain strength, shear resistance and erosion resistance. Cemented dams have a wide range of dam construction materials, different proportions of sand and gravel in raw materials, large aggregate gradation changes, and large discreteness. ...
