基底原状土置换在超限回填边坡中的运用分析

Analysis of the application of undisturbed soil replacement in backfill slopes with exceeding height limits

贵州山区工程建设用地紧张,场地高填深挖现象普遍。以贵州省某县城一弃土场为例,研究分析了坡脚强支护和基底原土置换在超限回填边坡中的应用。通过经济、技术、工期和弃土能力等方面的对比分析,超限回填边坡采用基底原土置换的方案,具有技术可靠、性价比高、工期短等优点,是一种相对科学可行的方案。

The construction land in mountainous areas of Guizhou is tight,and the phenomenon of high filling and deep excavation of the site is common.In this paper,the application of strong support of slope foot and replacement of original soil in overfill slope is studied and analyzed by taking Chengyi abandoned soil field in a county of Guizhou Province as an example.Through the comparative analysis of economy,technology,construction period and the ability of soil abandonment,the scheme of replacing the original soil of the overfill soil slope has the advantages of reliable technology,high cost performance and short construction period,and is a relatively scientific and feasible scheme.
