| 摘 要： | 针对深厚覆盖层上修建高土质心墙堆石坝提出了一个新型结构体系,即直接在覆盖层上建"混凝土盖板",混凝土盖板中设置大型廊道,可以在大型廊道中施工修建防渗墙,由覆盖层中的防渗墙、混凝土盖板及以上的坝体形成完整的防渗体系。对该新型坝体结构进行了有限元计算,得到了新型结构的应力、变形规律,并评价了这种新型结构的结构安全性和适应性。

| Abstract: | A new structure system for the high rockfill dam with earth core built on deep overburden layer is proposed, which is to construct concrete slab directly on the deep overburden layer, and to build concrete cut-off wall in the large corridor in the concrete slab. The cut-off wall in deep overburden layer, the concrete slab and the upper dam constitute a complete anti-seepage system. The new dam structure is analyzed through finite element calculation, and the stress and deformation law of this structure are acquired. Moreover, the safety and adaptation of the structure are evaluated to be feasible. |
