哥伦比亚的1.2MW 的索戈莫索(Sogomoso)水利水电枢纽已完成设计阶段,正进入利用外资的招标阶段。该坝坝型为 CFRD,坝高195m,坐落于两岸非常陡峭的河谷,大部分地基是破碎的强风化砂岩,所以设计中采用了嵌入坝肩的趾板作为基础的延长段。考虑到河床的狭窄以及施工期间的防洪要求,围堰应能承受漫顶,为此将上游RCC 围堰与主坝连为一个整体,并在下游围堰脚布置 RCC 保护。
The 1.2MW Sogomoso hydroelectric hub in Colombia has completed the design phase and is entering the tender phase of utilizing foreign capital. The dam is CFRD, with a dam height of 195m. It is located in a very steep valley across the Taiwan Strait. Most of the foundation is crushed strongly weathered sandstone. Therefore, the design uses plinth slats as the extension of the foundation. Considering the narrow riverbed and the flood control requirements during construction, the cofferdam should be able to withstand the overpressure. Therefore, the upstream RCC cofferdam should be connected with the main dam as a whole, and the RCC protection should be arranged at the foot of the downstream cofferdam.
