同马大堤属长江一级堤防,位于长江中下游左岸安徽省境内.由于大堤修筑在长江和皖河Ⅰ、Ⅱ级阶地或高漫滩上,堤基土体类型复杂,因而有必要对堤基结构进行分类,以利于堤防除险加固.根据堤基土体类型及地质特征,进行二级堤基结构分类,第一级将堤基分为粘性土堤基和砂性土堤基,第二级根据粘性土、砂性土的分布与组合关系进行分类.堤基结构分类为堤基渗透变形、堤坡稳定性分析和堤基工程地质分段评价提供了方法和依据.
同馬大隄屬長江一級隄防,位于長江中下遊左岸安徽省境內.由于大隄脩築在長江和皖河Ⅰ、Ⅱ級階地或高漫灘上,隄基土體類型複雜,因而有必要對隄基結構進行分類,以利于隄防除險加固.根據隄基土體類型及地質特徵,進行二級隄基結構分類,第一級將隄基分為粘性土隄基和砂性土隄基,第二級根據粘性土、砂性土的分佈與組閤關繫進行分類.隄基結構分類為隄基滲透變形、隄坡穩定性分析和隄基工程地質分段評價提供瞭方法和依據.

Tongma levee As, a grade Ⅰ levee of the Yangtze River, is located on the left bank of the middle and lower reaches of the Yangtze River in Anhui Province. Due to the levee constructed on the Yangtze River and the Wanhe River terrace Ⅰ,Ⅱ with complicated earth structure, so it is necessary to classify the levee foundation structure for removing the danger and reinforcing the levee. According to earth classification and geological characteristics of the levee, 2 levee structures are classified : classification Ⅰ are cohesive soil levee foundation and sandy levee foundation, classification Ⅱ is classified according to the distribution and constitution of cohesive soil and sandy soil. The levee classification provides the method and basis for analysis of levee foundation seepage deformation, levee slope stability and segmented evaluation on levee engineering geology.
