Summing up of slant drilling hole grouting of the Jintian reservoir s stone masonry dam;
金田水库砌石坝斜孔造孔灌浆总结
In order to prevent seepage in stone masonry arch dams, the dam body is usually composed of different materials.
砌石拱坝为了防渗通常使坝体由不同材料组成,由于不同的材料具有不同的弹性模量,这类坝可称为成层异弹模拱坝。
Seepage proof facing plate or watertight concrete layer often locates in stone masonry arch dam.
在上游面或内部偏上游处设置了混凝土防渗层的砌石拱坝为成层异弹模坝。
Reinforcement design for Shichengz masonry arch dam;
石城子水库砌石拱坝除险加固设计
Integrated with contact theory, the finite element method software ANSYS is used to calculate the interface between the new and the old mass of dam after the heightening and thickening of masonry arch dam.
对砌石拱坝加高培厚中的新、老坝体结构面,用有限元软件ANSYS结合接触理论进行计算,并分析结果得出:温升、水压力和淤沙压力使结合面上的接触压力增大,从而接触摩擦应力较大,有利于结合面的结合,而结合面在温降的作用下有脱离的趋势。
In recent years, the types of masonry arch dams in Fujian are gradually diversified and optimized, and develop to new, light, high and thin types.
福建省的砌石拱坝设计体型日趋多样化 ,并向新颖、轻、高和薄的方向发展 。
The dam of Tapangou Reservoir is a dry-laid masonry dam with grouted stone gravity wall,its strength and stability do not satisfy the standard request and should be enhanced through consolidation grouting and curtain grouting.
塔盘沟水库大坝为浆砌石重力墙式干砌石坝,其强度及稳定性均不满足规范要求,通过坝体固结灌浆和帷幕灌浆提高大坝的强度和稳定性,这里着重介绍了灌浆工程的设计和施工工艺的控制。
