广西铁路沿线红土地质特性试验研究

EXPERIMENTAL RESEARCH ON GEOLOGC CHARACT ERISTICS OF LATERITE ALONG RAILWAYS IN GUANGXI AREA

通过大量的现场调查和分析试验，本文对广西红土的成因类型、地层时代进行了系统划分．对其物质成分、结构特征和物理力学性质进行了分析总结，揭示了各类红土性质的共性和差异规律，尤其是胀缩性规律，推荐了路堑边坡坡率，从而为理论研究和工程建设提供了依据。

According to a large amount of field investigations and experiments, In the paper laterite in Gnangxi Area, has been systematically divided into genetic types and stratigraphic formations. Its mass composition, structure characteristics as well as its physical-mechanical properties have been analysed and summarized. Further, the general character and diversity law of the laterite, especially laws of swelling and shrinkege, are revealed, and gradient of cutting slope is recommended. Therefore, the paper provids a basis for theoretic study and engineering construction.
