Problems solved by technology

For sedimentation simulation experiments, such a conventional operation process is not only a waste of time, but also some collapses will occur during the section cutting process, so the accuracy of the measured data is not high enough, so that the authenticity and reduction degree of the established 3D model are not high

Embodiment 1

[0026] A method for restoring the internal structure of deposition simulation in this embodiment includes the following steps:

[0027] 1) Lay sediment in the tank according to the requirements of the sediment simulation experiment, then inject water for the experiment and observe the experimental phenomenon, release the water after the observation, and set aside;

[0028] 2) Put the container after step 1) and the moisture-saturated sediment together into refrigeration devices such as cold storage and freezer for quick freezing treatment, and the moisture-rich sediment freezes to form solid sediment; the temperature of the quick freezing treatment is -20 ℃, and the freezing time is 24 hours; because the sediment is saturated with water, the sediment can be quickly frozen into a solid, so that its internal sedimentary structure can be kept to the greatest extent;

Abstract

The invention discloses a sedimentation simulation internal structure recovery method. The method comprises the following steps: 1) paving sediments in a container according to requirements of a sedimentation simulation experiment, then, injecting water for conducting the experiment, observing the experiment phenomenon, discharging the water for later use after observation is finished; 2) performing rapid freezing treatment on the container and the hydrated sediments, and freezing the hydrated sediments to form a solid sediment; 3) taking the container and pouring the container with warm wateralong the inner wall of the container, gradually melting the outer edge of the solid sediment until the solid sediment is taken out; 4) controlling the slice thickness and longitudinally slicing thetaken-out solid sediment to obtain a series of longitudinal slices of the solid sediment; and 5) sorting and numbering the obtained series of longitudinal slices according to the sequence of the slices, so that the internal structure of a sedimentation simulation result can be recovered. According to the method in the invention, the internal structure of the sediments can be kept to the largest extent, and errors caused by other methods are eliminated.

Description

technical field [0001] The invention relates to the technical field of deposition physics simulation, in particular to a method for restoring the internal structure of deposition simulation. Background technique [0002] Sedimentary simulation is an important experimental method and technical method in the theoretical study of sedimentology, which can be divided into numerical simulation and physical simulation. Among them, physical simulation is an indoor simulation of the physical process of sediments. By simulating the deposition conditions at that time, the deposition process of natural sediments is restored in the laboratory. Since the 1980s, researchers in different countries have rebuilt or newly built laboratories of different scales suitable for sand body simulation of rivers, deltas, fan deltas, alluvial fans, and lakes. Most of these are large-scale flume simulations. , of course, there are also some small and medium-sized depositional simulation experiments that...
