雅鲁藏布江堤防主要工程地质问题

The Main Engineering Geological Problems of the Brahmaputra Embankment in Tibet

随着经济的发展,雅鲁藏布江流域堤防的重要性日益显现,而雅江堤防堤基多以砂性土为主,堤身也多由砂砾卵石填筑而成,其与常见的黏性土质堤防有着不同的工程特性。通过对雅江堤防堤基的地质结构分类,进而分析雅江堤防存在的主要工程问题,以期对于西藏类似堤防产生一定借鉴意义。

With the development of economy,the importance of the Brahmaputra basin embankment increasingly apparent. Most of the Brahmaputra basin embankment foundation is mainly in sandy soil, and most of the levee is filled with gravel pebl）les,which is different from the engineering characteristics of the common sticky soil embankment. The author classifies the geological structure of the Brahmaputra basin embankment foundation ,and then analyzes the major engineering problems which existed in the Brahmaputra basin embankment ,in order to provide reference for the similar embankment in Tibet.
