摘要
土石坝的防渗体已从过去单一的粘性土发展至今的风化料、砾质土、掺和料。能否做高土石坝的防渗体,其抗渗性能及渗流稳定至关重要,文章对拟用于261.5m级高坝的防渗土料进行了抗渗流稳定性研究。
Nowadays weathered material or gravelly soil or admixture has been used in making impervious cores of earth-rockfill dams in addition to clay soil. Whether or not they can be used for an impervious core of a high earth-rockfill dam depends on their seepage resisting properties and seepage stability. The paper deals with the study of seepage resisting properties and seepage stability of the impervious materials which are proposed to be used for construction of a 261.5m high earth-rockfill dam.
