发明提供一种土质心墙堆石坝与混凝土重力坝的组合坝型及其建造方法。该组合坝型包括土质心墙堆石坝段和混凝土重力坝段，以及衔接土质心墙堆石坝段和混凝土重力坝段的混凝土过渡坝段。所述土质心墙堆石坝段从上游侧到下游侧依次为上游堆石区、上游反滤区、土质心墙区、下游反滤区和下游堆石区。所述混凝土过渡坝段从上游侧到下游侧依次为上游衡重式挡墙、中间俯斜式重力坝和下游衡重式挡墙。该组合坝型的建造方法包括截流导流施工、坝基基槽开挖施工、混凝土过渡坝段施工、混凝土重力坝段施工、土质心墙堆石坝段施工等步骤。该组合坝型适用性广泛、经济性好且防渗效果好，具有广阔的应用前景。 The invention provides a soil core wall rockfill dam and concrete gravity dam combined dam type and a construction method thereof. The combined dam type comprises a soil core wall rockfill dam section and a concrete gravity dam section, and a concrete transition dam section for joining the soil core wall rockfill dam section with the concrete gravity dam section. The soil core wall rockfill dam section consists of an upstream rockfill area, an upstream inverse filter area, a soil core wall area, a downstream inverse filter area and a downstream rockfill area in sequence from upstream side to downstream side. The concrete transition dam section consists of an upstream balance stop wall, a middle pitching inclined gravity dam and a downstre
