浇筑式沥青混凝土心墙土石坝在我国是一种崭新的坝型,浇筑式沥青混凝土防渗结构的最大特点是适合于寒冷地区冬季施工,其耐久性,防渗可靠性,抗冲击性能等均优于其它防渗结构,且施工方便、工期短、造价低。最近20多年的工程实践表明,这种坝型的设计与施工仍停留在经验阶段,许多中小型工程由于种种原因,在施工过程中没有进行系统的基本资料观测或较深入的试验研究。因此,结合已建、在建和正在设计的工程进行浇筑式沥青混疑土材料基本性能的试验研究,对推广应用这种坝型是十分有意义的,同时也可为水利工程及其它工程的设计与建设提供有价值的参考。
Pouring asphalt concrete core earth dam is a new type of dam in our country. Pouring asphalt concrete impervious structure is most suitable for winter construction in cold area. Its durability, anti-seepage reliability and impact resistance Better than other anti-seepage structure, and the construction is convenient, short construction period, low cost. The engineering practice of the past 20 years shows that the design and construction of such dams remain in the experience stage. Many small and medium-sized projects do not conduct systematic basic data observation or more deep experimental studies during the construction due to various reasons. Therefore, it is of great significance to popularize and apply this type of dams based on the experimental study on the basic properties of cast-in-place bitumen mixed with existing, under construction and designing projects, and also can be used for water conservancy projects and other projects Design and construction provide valuable reference.
