Problems solved by technology

[0003] Most of the existing tests on the dry and wet environment treatment of soil are aimed at the soil after disintegration. There are no related experiments on the volume change during the disintegration process of the rock mass, and there is no systematic research on the volume change under the influence of vertical pressure and dry and wet environment during the disintegration process of the rock mass.

Abstract

The invention discloses a test apparatus for measuring volume change of carbon mudstone in a disintegration process and a test method of the test apparatus. The test apparatus is divided into three portions, wherein a first portion is a test apparatus, the test apparatus is an organic glass barrel with a water outlet pipe and a water supply pipe on the bottom; a second portion is a loading apparatus, and the loading apparatus is a lever loading instrument arranged on a base; and a third portion is a measurement apparatus, and the measurement apparatus is a support with two ends provided with a dial indicator. The three portions are tightly combined and work together. When in test, the organic glass barrel is first fixed, then a test soil body is arranged on permeable stone, a loading frame is mounted, and a weight is arranged, so as to simulate the vertical pressure of the carbon mudstone in a soil layer. A water circulating environment of the carbon mudstone is simulated by virtue of the water inlet pipe and the water supply pipe of the test apparatus, so that a volume change rule of the carbon mudstone in the disintegration process can be obtained.

Description

technical field [0001] The invention relates to a test device for measuring the volume change of carbonaceous mudstone during the disintegration process. The device can simulate the volume change law of carbonaceous mudstone under the influence of vertical pressure and dry and wet environment during rock disintegration. The invention also relates to the test method of the test device. Background technique [0002] At present, the volume change of embankment soil has become a problem that cannot be ignored in the field of highways and railways, and traffic accidents caused by the volume deformation of embankment soil occur from time to time. Especially the volume deformation of the embankment is more serious after being affected by the dry-wet cycle, and more and more projects use carbonaceous mudstone as embankment filler. How to ensure the safety of the carbonaceous mudstone embankment during construction and after completion has become a One of the most critical issues f...
