【摘要】 CSG是一种源于日本的筑坝技新术,贵州省道塘水库应用了该技术,充分利用了河床里的天然砂砾石,加快了施工速度,取得良好的效果。通过室内试验研究,初步了解了CSG的材料性能,通过现场试验和围堰施工,初步掌握了CSG施工的关键控制环节。文中介绍了该技术在道塘水库应用的研究、设计成果的应用经验。更多还原

【Abstract】 CSG(Cemented Sand and Gravel)dam construction technique is a new dam construction technique from Japan.In Daotang Reservoir Project the technique is applied to construct the cofferdam,by which the natural sand and gravel in the river bed have been fully used as the CSG material,and then the construction progress has been quickened with better effect.Based on the indoor experimental study concerned,the material characteristics of the material has been known primarily and the key links of CSG construction has been obtained basically through the in situ experiment and the construction of the cofferdam.The application study,design and the construction experience of the technique are introduced herein.更多还原
