Description

technical field [0001] The invention relates to a rock and soil body weathering test system and a test method, in particular to a rock and soil body with a high content of clay minerals in the process of water loss or water absorption under different temperature, humidity and wind velocity conditions and the macroscopic Structure evolution test system and test method. Background technique [0002] The weathering process of rock and soil under different temperature, humidity and wind velocity environments is one of the most basic research topics for a series of rock and soil engineering structural stability, such as slope engineering, tunnel engineering, foundation reinforcement, mining engineering and water conservancy engineering. First, it has very important scientific value and engineering significance. [0003] Weathering is one of the main factors affecting the long-term stability of rock and soil structures, especially for weakly cemented rock and soil bodies such as ...

Problems solved by technology

[0009] If the rock and soil sample is taken out from the constant temperature and humidity box, and then the water content measurement and the macro and micro structure records are respectively carried out, the temperature and humidity in the constant temperature and humidity box will be lowered first when the sample is taken out of the box. Affected by the external environment of the box, after the water content of the rock and soil mass and the macro and micro structure are tested, it will be placed in a constant temperature and humidity box to continue the test. The temperature and humidity environment in the constant temperature and humidity box will be adjusted to the set The value process will affect the test results. Secondly, the repeated manual testing work greatly reduces the test efficiency. In addition, the rock and soil samples are tested after they are taken out of the constant temperature and humidity chamber. Influenced by the parameters of the sample, and the macro-microstructure of the sample changes in real time with the water content, therefore, it is necessary to develop a rock and soil weathering test system. Long-term stability of the environmental conditions during the soil weathering test, while monitoring the water content and the evolution of the macro-micro structure over time during the rock-soil weathering process, so as to determine the weathering evolution law of the rock-soil mass accurately and quantitatively
