【Abstract】 Deeply-embedded gravity-frame retaining structure,as a new type of retaining structure,combines the features of gravity retaining structure and frame retaining structure,and has the advantages of convenient construction and low cost. Numerical analysis method is used to study the behavior of this retaining structure and its main influence factors,such as the depth,the replacement ratio,and the top position of reinforced zone. It is shown that the moment and displacement of this structure decrease remarkably,so this retaining structure has extensive prospect of application in engineering practice. Finally,the excavation of Yaojiang Building is analyzed,and the theoretical results are close to the measurement data. The reasonability of calculation model in this paper is verified.更多还原
