Subgrade Diseases And Prevention In Gobi Special Soil Of The Yanqi Basin

Subgrade diseases is a focus and difficult problem in Highway engineering. Saline soil, aeolian sand and other adverse geological phenomena are widespread in Xinjiang Yanqi Basin. Highway subgrade diseases are very common in this region, such diseases affect the normal operating and road maintenance adversely, otherwise, the diseases characteristics showing varies of factors. This text studying on the typical highway engineering, starting from a full understanding of the physical mechanical properties and engineering characteristics of saline soil, based on research foundation data, analysis the engineering environmental characteristics of the region, combined with laboratory and field test data and fixed-point observation sections test data, a comprehensive analysis of the causes of defects. Further discussed the mechanism under the action of multiple factors comprehensive road damage. Through a comprehensive analysis of the existing experimental and theoretical results, considering the geology, climate, and environment characteristic of this area, using engineering geological analogy analysis method to summed up a reasonable engineering method for the treatment and prevention of Yanqi region highway diseases. Moreover, this text expounded construction technology and key points construction about saline soil and aeolian sandy soil subgrade, meanwhile, offered a proposal of geosynthetics using.
