Abstract

The invention provides a method for field preservation of loose rock core original state specimens. The method comprises the following steps: calculating and proportioning reagents according to the total amount of loose rock core samples; preparing a sample box according to the size of the sample of the loose rock core; putting the sample of the loose rock core into a sample box, pouring a reagentinto the sample box, and standing until the reagent is solidified; preparing the label of the sample of the loose rock core and adhering the label to the outer wall of the sample box to form the original state specimen of the loose rock core. The invention provides a method for preserving loose rock core undisturbed specimens in the field. The process flow is simple, actual operation of workers is facilitated, manufacturing can be conducted on a field site, the rock structure of a sample of the loose rock core can be well guaranteed, long-term storage and transportation are facilitated, subsequent workers can know the fracture phenomenon of a fracture surface layer more visually, comprehensively and accurately, and subsequent earthquake and geology analysis can be conducted.

Description

technical field [0001] The invention relates to the technical field of seismic geological analysis, in particular to a method for preserving undisturbed samples of loose rock cores in the field. Background technique [0002] A fault is a structure in which a rock layer or rock mass has obvious displacement along the fracture surface. Faults are widely developed in the crust. The physical objects of the faults record the petrological characteristics and geological environment information of the specimens, as well as the fault's dip, dip, overturning angle, flanking angle and other structures. information, which can fully reflect the nature of faults. Fault hand specimens visually reproduce the normative, comprehensive and accurate dislocation phenomenon, which is the basis for seismic geological analysis. [0003] Today's drilling method is a common method for studying concealed active structures. In the field work, rock core sections are found from time to time, but due to...
