摘要
A new complete loess profile has been found in Baoji region of the Loess Plateau in recent years. Based on this profile, this paper presents a study of the features of loess engineering geology. The study is based on a detailed field investigation of typical loess section at Jiacun Terrace in Chenchang of Baoji region. The results show that 1) there is an inverse correlation between density and porosity ratio; 2) there is a positive correlation between liquid limit and plastic limit along with the borehole depth; 3) there is an inverse correlation between modulus of compression and compressibility factor; and 4) there is an inverse correlation between internal cohension and internal friction angle with large variation range along the borehole depth.
