Abstract: In order to study drying shrinkage characteristics of loess in loess area surface, through the study of indoor test of volume shrinkage properties of saturated remolded loess after surface. The drying shrinkage volume were measured with liquid paraffin replacement method, analysis results show that, the whole process of shrinking the sample preparing remolded loess can be divided into three stages, namely the normal contraction stage, residual contraction phase and zero contraction phase. Most of the shrinkage occurs in the saturation stage specimen, the shrinkage degree not only in the longitudinal change, but also the obvious changes in the horizontal. Due to the contraction process will produce a series of non tectonic fissures in the Loess in vivo, change the mechanical properties of loess body in certain extent, which have significant influence on the engineering geology of Loess plateau. Finally, the variation characteristics of water on the specimen by drying shrinkage rate of loess soil, porosity, saturation and physical parameters such as volume shrinkage, and shrinkage characteristics curve unearthed.
