| Because of special geology~ geography conditions and the properties of bess in Gansu province many high embankments and high-cutting slop built in Loess District exits many problems to be solved urgently. Based on the collected documents and the investigation on the subgrade filled by bess in Gansu province this paper confirms the range of slope of special subgrade in Loess District, analyses physical and mechanics properties of original appearance and compacted earth, provides the effective method of high embankment and high- cutting slop stable analyst, draws up the relative programmer. This paper finds out the effect factor of the stability. Through investigating and evaluating the form of slop built in Gansu province we can put forward the reasonable transect, which applied in special subgrade filled by bess in Gansu province. Finally, the conclusion of bess stability provides the base for engineering design and construction. |
