( Guangzhou Design Institute, Guangzhou 510620, China)Abstract: By the introduction of municipal transportation project in Pearl River New Town Central District, the article demonstrates the impact of the underground space'8 development on the underneath shield-structure tunnnel. The protection measure to the existed shield-structure tunnel by the close pile plus cover board was presented, as well as the contrast between the displacement change during the construction and the testing result was done. The protection measure is comfirmed to be effective.
