古洞口面板堆石坝临时渡汛方案研究

古洞口大坝是一座在深覆盖层上修建的混凝土面板堆石坝,因多种因素的影响,工期严重滞后,1997年坝体渡汛面临严峻的考验.为了挽回工期,针对当时现场实际,拟定了两个方案进行研究,确认大坝临时断面挡水渡汛方案合理可行,易于实施,通过严密组织、科学施工,最终实现了工程安全渡汛,创造了可观的效益.

Research of Scheme of Temporary Flood Control at Gudongkou Concrete Face Rockfill Dam

Gudongkou Dam is a rockfill dam on the deep alluvium covering the valley floor.Because of influences of multiple factors,construction period was lagged severely;and the rockfill dam was up against austerely a trial of the flood control in 1997.In allusion to the local fact then and there,of which two schemes had been researched for redeeming the time limit for a project. The scheme was confirmed of reasonable and doable;and it was actualized easily;the flood was blocked and controlled by the temporary section of the dam.Finally,the flood control for the project was achieved safely by rigorous organization and scientific construction;and the considerable economic effect was created.
