Abstract

The invention discloses a preparation method of a multi-karst cave geological model. The preparation method comprises the steps: firstly, extracting information of a to-be-simulated geological model;then preparing a similar simulation material, a model box, a karst cave core model and a solvent flow pipe according to the extracted geological model information; secondly, selecting corresponding sizes of karst cave core molds according to geological model information, placing the karst cave core molds at corresponding positions, connecting the adjacent karst cave core molds in series through solvent circulating pipes to form a circulating pipeline, reserving an inlet and an outlet extending out of the model box at the head end and the tail end of the circulating pipeline, and then injectingthe similar simulation material into the model box for pouring; after curing, injecting a solvent capable of dissolving the karst cave core molds into the circulation pipeline through the solvent circulation device, dissolving and bringing out the karst cave core molds, and forming a simulated karst cave space; and preparing the multi-karst-cave geological model. The method can be used for various models with holes inside, the holes and the surrounding area are integrated, and reality constraint and stress conditions can be better simulated.

Description

Technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a geomechanical model technology, in particular to a method for preparing a multi-karst cave geological model, and a method for forming an internal cavity in a geological model test, which solves the problem that the internal cavity of the model in the geological model test is difficult to simulate The problem. Background technique [0002] The karst area in my country is vast, and karst geological conditions are often encountered during project construction. The karst caves have caused great troubles to the progress of the project. When engineering construction is carried out in a karst area, the bearing capacity of the upper foundation of the karst cave becomes the key to affecting the quality of the project. Research on the bearing capacity of the upper foundation of karst caves is a hot topic in karst geological foundation engineering. In the current indoor model test re...
