Analysis on Face Slab Extruding Rupture of High CFRDs
摘要
Abstract
Taking a high CFRD as study case, the causes of face slab extruding rupture are analyzed. It is found that large deformation and non-coordination deformation of rockfill as well as cavity zones under face slab are the key causes. Based on existing engineering experiences, it is proposed to conduct deformation control and deformation coordination in design phase by considering rockfill and face slab as a whole. Structural defects such as the interface of horizontal construction joint being not perpendicular to face slab should be avoided. At the lower part of upstream face slab, fly ash or fine sand can be used for replacing clay blanket in order to increase the abilities on silting and filling and self-healing of overall anti-seepage system.关键词
