Finite element method for computations of active earth pressures acting on L-shaped retaining walls with reduced friction coefficients of base bottoms

In this paper, considering the retaining structure—L type retaining wall used in section from Golmud to Lhasa, Qinghai-Tibet railway,we test the earth pressure or frost-heave in a frost-thaw cycle for one year,and we study several different analytic models of earth pressures and frost-heave.

The paper elaborates the quality control and construction supervision on large-size retaining walls, including its measurement, locating, setting out, material, pit excavation, masonry grouting, setting of settlement and expansion joints, preforming of drain hole, and joint pointing on masonry surface, etc.
