通过调绘、钻探、物探、室内试验的综合勘察方法,查明了滑坡及周边环境的地层岩性、地质构造及水文地质条件,提供了滑坡治理设计所需的岩土参数,为路线施工方案提出了科学合理的建议。作为一种新型浅层地震勘探方法,采用瞬态瑞雷波法并结合折射波法,查明了滑坡面的空间分布形态,探测效果良好,也弥补了钻孔间地质资料的不足,为今后瞬态瑞雷波法广泛运用于滑坡勘察提供了一个良好的佐证。
通過調繪、鑽探、物探、室內試驗的綜閤勘察方法,查明瞭滑坡及週邊環境的地層巖性、地質構造及水文地質條件,提供瞭滑坡治理設計所需的巖土參數,為路線施工方案提齣瞭科學閤理的建議。作為一種新型淺層地震勘探方法,採用瞬態瑞雷波法併結閤摺射波法,查明瞭滑坡麵的空間分佈形態,探測效果良好,也瀰補瞭鑽孔間地質資料的不足,為今後瞬態瑞雷波法廣汎運用于滑坡勘察提供瞭一箇良好的佐證。

Through comprehensive prospecting methods, such as annotation, probe drilling, geophysical exploration, indoor tests, the conditions with respect to formation lithology, hydrogeology of the landslide and its surrounding environment are checked, through geologic structure and which the geotechnical parameters for treatment design are offered and the scientific and rational advices on route construction are proposed. As a new method for prospecting shallow earthquake, transient Rayleigh wave method combined with refraction method is adopted to check out the spatial distribution of the landslide surface. The prospecting effect is good enough to make up the shortage of geological materials evidence for extensive application of transient Rayleigh wave method about drilling holes and to supply a good in landslide prospecting.
