The present invention provides an indoor soil burning simulation test device and the test method thereof. A fan and a temperature sensor are arranged in a resistance furnace, a mesh screen is arranged on an opening of a bottom plate of the resistance furnace, the resistance furnace is placed on a triangular support, a case is placed below the triangular support, and a test soil core is placed in the case. The case is a cylinder formed by connecting two semi-cylinders through hinges, the inner wall face of the cylinder is lined with an asbestos heat insulation layer, each semi-cylinder is provided with a vertical rectangular opening, a ruler and a plurality of horizontal rectangular openings, the base plate is in sliding fit with the cylinder, and two bolts on the base plate extend out of the two vertical rectangular openings respectively and are fixed through nuts. The temperature and humidity sensors extend into the test soil core from each horizontal rectangular opening. According to the invention, undisturbed soil burning tests with different burning temperatures and durations can be carried out indoors, the temperature and moisture content changes of soil with different depths in the soil core in the roasting process can be measured in real time, and the device has the characteristics of convenience in test and measurement and portability.
Description
technical field [0001] The invention relates to the experimental technical field of post-fire mud-rock flow disaster mechanism and prevention research, in particular to an indoor soil fire simulation test device and a test method thereof. Background technique [0002] After a mountain forest fire occurs, there is a high probability of post-fire debris flows that are different from traditional debris flows near the burnt areas. Compared with non-fire debris flow, the source initiation is significantly different, which is closely related to the changes in soil physical properties and water properties caused by the high temperature roasting of the understory soil during the forest fire burning process. Due to the uncertainty of the time, place, temperature, and duration of forest fires in mountainous areas, the research in this area has caused great difficulties, and the cost of planning artificial forest fire experiments is high and it is difficult to control the scope of fire...
