Subgrade Design and Construction Technology for Saline Soil Area

Abstract:

The design scheme and engineering construction technology are proposed for an accommodation highway subgrade on the basis of forming reasons and hazard analysis of saline soil in Xinjiang region. In the design, major measures adopted include basement replacement, setting aeolian sand layer and composite geotextile layer, strengthening the subgrade waterproofing and drainage, antiseptic treatment of structures, etc. This paper introduces the subgrade design and construction technology, of which the implementation and application on the test section have achieved a favorable effect and can be taken as the basis for design and construction of similar saline soil subgrade.
