Study on Durability of Railway Subgrade Structure Based on Indoor Sand-Blown Model Experiment
Abstract Sandstorm erosion plays an important role in destroying the durability of structure of railway subgrade, so this research studies the mechanism and factors that sandstorm erosion erodes the railway subgrade structure in Northwest Loess Area through indoor sand-blow model experiment. The experiment uses the sand-blasting machine to produce the sand flow to erode the railway subgrade model which components is the improved loess, and simulates the sand erosion by controlling the velocity and time of sand flow. After completing the test, the research elaborates the impact of sand erosion on the durability of railway subgrade structure which provides certain theoretical guidance for the sandstorm prevention design and the control of the existed sandstorm disaster of railway in Loess Windy Area, according to measure the density, moisture content, quality and unconfined compression strength of the experimental models.
