沥青混凝土做为水工建筑物的防渗材料,于二十年代末开始应用于大坝工程,由于它有防渗抗震性能好,适应变形能力强,施工速度快,工程量小和成本较低等优点,在半个多世纪中,世界上已有几百座大坝成功地应用了沥青混凝土为心墙、斜墙防渗体和堵漏工程。目前,关于水工沥青混凝土防渗层厚度的设计,尚无统一的公式;对于大坝防渗斜墙的厚度设计,一般按耐久性、抗渗性、水压力、冲击波压力、稳定性和施工工艺来考虑,对于大坝防渗心墙的厚度设计,一般按坝高来考虑,上述情况,有关资料已有介绍。本文是根据所掌握的国内外的资料的统计和分析,提出以坝高与防 As an impermeable material for hydraulic structures, asphalt concrete is applied to dam works since the late 1920s. Due to its good anti-seepage and anti-seismic performance, high adaptability to deformation, high construction speed, small construction cost and low cost Etc. In more than half a century, hundreds of dams in the world have successfully applied asphalt concrete as a core wall, sloping wall anti-seepage body and plugging engineering. At present, there is no uniform formula for the design of hydraulic asphalt concrete impermeable layer. For the design of the thickness of impervious sloping wall of a dam, it is generally designed according to the durability, impermeability, water pressure, shock wave pressure, stability and construction Process to consider, for the dam impermeable wall thickness design, generally according to dam height to consider the above situation, the information has been introduced. This article is based on the statistics of domestic and foreign statistics and analysis, proposed to dam height and defense
