某大型瀑布设计方案的选择研究

根据某工程的实际情况,提出四叠瀑和滑瀑两种瀑布方案,通过两种方案的瀑布构造、堰上水头、设计单宽流量和循环水泵选型的比较,得出了滑瀑方案更合适、能耗更小的结论。     

挂篮悬臂混合法施工技术-续

B、混凝土浇注，先浇一侧，再浇另一侧，为避免施工中劲性骨架变形对已浇混凝土的影响引起混凝土开裂，采用水箱压重方式控制。具体作法为，预先在底板下面安设容量为46立方米水箱和容量为40立方米胶囊各一个，并在劲性骨架前端上节点处安置压重10吨，总计96吨？一边浇混凝土，一边放水，直至混凝土浇完为止。     

瀑布景观赏析与设计

从研究瀑布的发生、分类,瀑布景观的组成以及瀑布落水的基本形式入手,探讨瀑布景观设计的理论基础.根据"得其性、仿其形、取其意"的原则进行瀑布景观设计.力求在瀑布设计中重视科学性与艺术性相结合,创造"源于自然,高于自然"的瀑布景观.

Landscape Formation and Protection of the Hukou Waterfall

Establishing geoparks is an effective approach to protect natural resources and promote local tourism industry. The national geopark of the Hukou Waterfall is an important geopark which attracts more than 2 million tourists per year. The Hukou Waterfall is formed by combination of multiple knickpoints due to the longitudinal profile analysis. Like other waterfalls in the world, the Hukou Waterfall will disappear in the future. Considering the mechanisms of waterfall evolution, this paper suggests establishing control engineering, preserving the water and soil in nearby region, and reinforcing the structure of waterfall to preserve the landscape of waterfall.

水表水头损失的计算和水表公称直径的选择

《建筑给水排水设计规范》（ＧＢＪ１５—８８）关于水表的水头损失计算和选择水表时水头损失值的校核控制范围，是据１９８８年前使用的水表参数而定．现行的水表性能参数与过去有很大差异，因此水表的水头损失计算式和选择水表的依据也应作相应的变动．笔者对此进行了讨论．     

圣维森特公园，卡马拉-德洛布什，马德拉，葡萄牙

圣维森特公园所在的基地表现出相当生动的背景。这是一个位于河流边上的平台,瀑布和悬崖限定了它的边界。这个平台曾作为耕地使用,构成了台地景观的一部分,并且表现出基地的环境特色。景观设计的意图是使台地成为一个休闲的露台,可由此远眺大西洋。园地设计的一个概念是成为火山作用博物馆的外部空间。博物馆用来解释火山现象,而园地则展示相关的水文状况及植被。水体和植栽因此成为园地的结构性元素:水体组织起了空间结构——溪流、抬升的沟渠以及水池;而基地特有的植栽则遍布整个台地。植栽正是一种可见的对于基地生态变化的解释和表达。…     

牛栏江引水工程盘龙江入口段瀑布堰体设计

以牛栏江引水工程盘龙江入口段防洪工程为例,介绍了该工程瀑布堰体的设计方案,着重对瀑布堰体的稳定性、应力及沉降变形进行了计算分析,计算结果表明:南段直坎段和北段三跌坎段瀑布在各荷载组合工况下,均能满足抗滑移、抗倾覆稳定性要求。
