SCHEME STUDY OF VERTICAL CUTOFF WALLUSED FOR DIKE ON ALLUVIAL FOUNDATION
冲积地基堤防垂直防渗方案研究

The structural types of alluvial foundation and seepage characteristics of the dike on the foundation are analyzed. Based on a great deal of seepage computation by using FE method,the applicable conditions and optimal design schemes of vertical cutoff wall for different types of dike foundation are studied. Moreover,the rational design standards of cutoff wall are also discussed.
