| 摘 要： | 杂填土,其成分复杂、结构松散、压缩性高,物理、力学性质不均匀,稳定性较差。如果在堆积之后不采取必要的加固措施,很容易发生地质灾害。本文结合山西省某高速铁路明挖段杂填土地层高边坡防护工程,利用数值模拟手段,采取放缓坡、加强坡脚、防渗处理、绿色防护等措施,结合监控量测信息反馈,提供了一种杂填土高边坡防护方案和思路,在很好地遵从“安全可靠、先进成熟、经济适用、保护环境”原则的基础上,解决了杂填土高边坡的防护问题,并经受了实践的检验。

| Abstract: | Miscellaneous fill has complex composition,loose structure,high compressibility,uneven physical,mechanical properties and poor stability.Without necessary reinforcement measures after the accumulation,it is very possible to bring geologic hazards.Based on a miscellaneous fill high slope protection project of a high-speed railway open cut section in Shanxi province,by using numerical simulation method and combining monitoring information feedback,this paper provides a scheme and some ideas in dealing with miscellaneous fill high slope,which provides a tested solution of miscellaneous fill high slope protection,by taking gentle slope,strengthening the toe,anti-seepage treatment,green protection,miscellaneous fill high slope protection,based on the principle of safe,reliable,advanced,mature,economical and environmental protection. |
