Abstract Research purposes: The geological characteristics of the Kunming basin are various and the geological conditions are complex, which has a great influence on the construction of the rail transit engineering. Due to the limitation of the exploration area, the study on the geological characteristics of the area is limited to the point at present, while the comprehensive and comparative study on the geological characteristics of the Kunming basin is less. This paper studies the regional geological characteristics and main engineering geological problems of Kunming Rail Transit Line 4, and provides the basis for taking relevant engineering measures.
Research conclusions: (1)Through the analysis of the geological conditions along Line 4, the differences of the geological characteristics and the main engineering geological problems of the micro-geomorphologic regions in the Kunming basin are systematically studied; (2)Combined with the engineering scheme and the main engineering geological problems, the stability of the site, construction scheme, retaining structure and drainage, karst and foundation treatment, anti-floating and anti-seepage of foundation pit are analyzed;(3)The paper is of great significance for understanding of the geological characteristics of the Kunming basin and can be used as a reference for the construction of the Kunming rail transit engineering.
