Abstract

t is significant to study settlement characteristics of the base layer in immersed tube tunnel for the settlement is quite large during the construction. Collects trial data of five sand replacement model based on engineering of Guangzhou zhujiang immersed tube tunnel, Guangzhou biological island-University city immersed tube tunnel, Guangzhou Zhoutouzui variable cross-section immersed tube tunnel, Tianjin Haihe immersed tube tunnel and Zhoushan shenjiamen immersed tube tunnel. Analyzes current study of the sand replacement model test and settlement characteristics, and summarizes current development and research progress. Analyzing the mechanism of settlement and silting impact in the base layer anti to the lack of settlement characteristic study and puts the further study and research ideas forward.
