摘　　要：均质土填筑的淤地坝易发生连锁溃坝,文中提出了将斜拉坝技术运用于淤地坝建设的设想,并与闸坝和液压升降坝2种方式进行了对比。在大厚度黄土地区修建斜拉坝,其主要技术难点是坝前拉索的锚固问题,对此开发设计了适用于深覆盖层上建设斜拉坝的抗拔基础结构。并对斜拉坝的防渗、泄洪等方式进行了探讨。Silt dams filled with homogeneous soil are prone to chain dam failure.The assumption of applying technology of cable-stayed dam to the construction of silting dam is put forward.The characteristics of the proposed technical scheme are compared with those of gate dam and hydraulic lifting dam.The anchorage of the cable in front of the dam is the main technical difficulty in the construction of cable-stayed dam in loess areas with large thickness.The methods of seepage prevention and flood discharge of cable-stayed dams are also discussed.It is of great significance to popularize new technology and new dam type cable-stayed dam.
