Abstract:

Due to the complex geological conditions of Guangzhou Metro project, for example the shield machines need to bore through karst caves and highstrength granite and cross underneath the Pearl River, a lot of shield machine construction experience has been accumulated during the construction, while numerous difficult problems have been encountered. The article makes an analysis on the geological conditions of Guangzhou Metro project and makes a study on and summary of the EPB shield machine construction technology under complex geological conditions.

Key words: Metro  , shield machine  , boring technology
