摘要
Considering the only retaining structure L-type retaining wall used in Golmud-Lhasa sectionofQinghai-Tibet Railway, the earth pressure and frost-heavingforce was tested in a frost-thaw circle for one year, and several different analysis models were studied.Comparedwith site test and theory analysis, it was found that the actual earth pressure is much larger than the designedearth pressure. Hence, a revised analysis model of earth pressure is put forward, which could include another possible force except slide triangle or frost heaving force. The model in this paper is only consider the thrust force other than failure sliding wedge.This model could be used as reference for the design and construction of similar projects.
