Structural plane shear strength size effect sample mold manufacturing method based on large number decomposition algorithm

Abstract

The invention provides a structural plane shear strength size effect sample mold manufacturing method based on a large number decomposition algorithm. The method comprises the following steps: (1) a series of sizes of coiled concrete samples on a structural plane are obtained according to test requirements of rock mass structural plane shear strength size effect research, and a length matrix is formed; (2) the form of a pouring mold is selected according to the length of the sample; (3) simultaneously pouring samples of which the lengths belong to the matrix by adopting a partition plate typemold; (4) pouring a sample of which the length belongs to the matrix by adopting a spliced mold; (5) designing the lengths of small side plates in the spliced side plates to form a length matrix; (6)calculating according to the large number decomposition algorithm; (7) obtaining the total required number of the small side plates and manufacturing the small side plates; and (8) the partition plates are inserted into the inserting grooves and the side plates to be spliced and then the partition plate type mold and the splicing type mold for pouring the series-size structural plane concrete samples are obtained. The utilization rate of the small side plates can be increased through repeated utilization during pouring, the vacancy rate of the mold is reduced and the sample manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to a method for making a sample mold for a shear strength size effect of a structural surface based on a large number decomposition algorithm, and belongs to the technical field of indoor physical and mechanical testing. Background technique [0002] In recent years, with the rapid development of my country's economy, some large-scale construction projects related to the national economy and people's livelihood, such as large-scale hydropower projects in the central and western regions, expressways and high-speed railways, deep resource mining, strategic oil reserves and nuclear power projects, have been implemented successively. The stability and catastrophic problems of large-scale open-pit mines are quite prominent, especially the landslide geological disasters of large open-pit mines, water conservancy and other slopes. A large number of literature studies have shown that the root cause of large-scale slope geological disasters...

Problems solved by technology

[0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a structural surface shear strength size effect sample mold manufacturing method based on a large number decomposition algorithm, which can avoid the steel damage caused by too many pouring molds for structural surface concrete samples of a series of sizes. Waste of materials and space can avoid the problem of insufficient splicing space caused by too small sample size. Multiple use during pouring can improve the utilization rate of small side plates, reduce the vacancy rate of molds, improve sample production efficiency, and reduce sample size. While the production cost is guaranteed, the accuracy of the sample size is guaranteed, the accuracy and scientificity of the test results are improved, and a scientific basis is provided for the design of the shear test of the rock mass structural plane with a series of sizes
