AI Technical Summary
Existing soil gas permeability testing devices cannot monitor the gas pressure distribution and permeability evolution along the height of the soil column in real time, resulting in inaccurate assessment results and failing to meet the needs of gas disaster prevention and control in geotechnical engineering.
By collecting multiple sets of historical data, a soil permeability mapping model is constructed. Combined with the permeability test of micro-unit soil samples and the optimization of air conduction angle, a mapping model of weight coefficients and constant terms is constructed to realize the permeability assessment and improvement of the waste soil layer. Non-engineering improvement methods are used to optimize permeability.
It enables precise assessment and dynamic optimization of the permeability of waste soil, reduces construction costs and complexity, improves the accuracy of permeability assessment and the scientific nature of engineering design, and reduces the risk of gas accumulation.
