Abstract: Comparing with the other frequently encountered soils, the Red Clay of Cretaceous Age has distinct properties due to its differences in degree of cementation, structural fabric and sedimentary formations. This paper presents the geological engineering properties of the area between Nancheng and Changguang Basin of MeiYing railway based on the engineering geological survey, insitu as well as laboratory test results. The properties of the Red Clay formation have summarized into three aspects. The railway construction recommendations are also proposed in the paper.

Key words: Red Clay of Cretaceous Age, Engineering Geological Characteristics, Engineering Recommendations；Soil Formations
