Abstract
As a new type of retaining structure, the geocell retaining wall has a broad application prospect in embankment and cutting slope protection. However, the traditional geocell retaining wall with constant cross-section has the disadvantage of high cost due to the use of large amount of geocell. In this paper, the safety factors of geocell retaining walls with different cross-sections are calculated. On the basis of the analysis of calculation results, a new geocell retaining wall with variable cross section is proposed for the purpose of optimum design. Furthermore, the suggested new geocell retaining wall with variable cross section is successfully applied in the relocation project of Yan’an Airport. In addition, the horizontal displacement and the earth pressure acting on the wall back are measured and the construction technology of the new structure is summarized.
