Abstract Research purposes: The Youxi Railway Station of the Xiangtang -Putian Railway lies in the low-terrain mountain area in Fujian Province with poor engineering geological conditions. Construction of this station needs excavation of high cutting slopes.To ensure the stability of the cutting slopes and keep the greening environment around the station, a new anchor technology developed in recentyears, namely, the compression dispersion -type anchorwas used. It can be described as the flexible ecosystem in the framework on slopping surface resulted from the three dimensions drainage system and the plants and biology protection owing to the spray sowing.
Research conclusions: In this paper, the introduction is given to the all-round reinforcement mechanism, design and calculation works of the compression dispersion -type anchor and the related matters for caution in the engineering application. Through the comparison and analysis of various anchor systems, the adapt ability of adopting the compression dispersion -type anchor to the Youxi Station was determined. The typical design calculation of the compression dispersion -type anchor was made according to the engineering geological conditions. The detailed discussion was made on the construction technology and the related matters for caution in the engineering application. The compression dispersion -type anchor presented in this paper can be as the reference to the design and construction of high cutting slopes for railway and highway in the mountain area with complicated geological conditions.
