Experimental method for visualization of biomineralization crystallization kinetics in fractured rock masses

Abstract

The present invention relates to an experimental method for visualization of biomineralization crystallization kinetics in fractured rock masses, comprising the following steps: S1, fabricating a test platform for simulating the biomineralization crystallization kinetic process in fractured rock masses; S2, solution preparation; S3, test operation; S4, visual observation; S5, three-dimensional acquisition; S6, establishing a mapping relationship between a two-dimensional deposition area ratio x and a three-dimensional volume fraction y; S7, in subsequent tests, using the test platform obtained in step S1 to perform steps S2-S3, then using a camera to perform time-series imaging of the flow channel, and obtaining a two-dimensional precipitation area ratio Xi at any observation time sequence through the two-dimensional images. By adopting the above technical solution, the experimental method for visualization of biomineralization crystallization kinetics in fractured rock masses of the present invention enables continuous time-series visual recording of the migration and settlement of effective products within rock fractures during the experiment, capturing the dynamic evolution of crystal growth, coalescence, and eventual clogging.
