据《世界建设》1978年10月号报道:美国小田纳西河上的方塔纳大坝,是四十年代建成的混凝土重力坝。该坝坝顶长721米,最大高度为146米,共分为41个坝段,用伸缩缝分开。第1～32坝段是直线坝段,第33～35坝段是弯曲坝段,其余的是左坝肩的各个坝段。由于坝址处河流向南流,下游坝面朝南,夏季受到强烈日光的照射,使坝体混凝土温度升高而膨胀,
According to World Construction Report, October 1978, the Fontanelle Dam on the Little Tennessee River was a concrete gravity dam built in the 1940s. The dam top 721 meters long, the maximum height of 146 meters, is divided into 41 dam sections, separated by expansion joints. The first to 32 dam sections are linear dam sections, the 33rd to 35th dam sections are curved dam sections, and the rest are each dam section of the left dam shoulder. Due to the southward flow of the river at the dam site and the downstream dam face facing south, it is exposed to strong sunlight during the summer so that the concrete temperature of the dam body will expand and expand,
