我省过去所兴修的中小型蓄水工程,一般是灌溉水库,设计库容较小,蓄水量每平方公里只达20万—30万公方,水利资源没有被充分利用。为了提高这些工程的防洪、抗旱能力并结合发电,目前已经有不少地区进行了土坝加高或扩建工程,根据各地的反映,土坝加高部分库面都很大,每加高一公尺所增加的库容,相当于原有坝高好几公尺的蓄水量;同时由于原有土坝断面较大,加高土方不多,工作量小,劳力容易安排,雨季施工影响也小。这是一项多快好省的建设措施,可以在全省范围内推广。为了使
The past small and medium-sized water storage projects in our province, which are generally irrigated reservoirs, have a small design storage capacity of only 200,000 to 300,000 square kilometers per square kilometer, and the water resources are not fully utilized. In order to improve flood control and drought resistance capacity of these projects and to combine power generation, there are already many earth dam dikes and expansions in many areas. According to the reports from all over the world, The added capacity of the footplate is equivalent to the water storage capacity of several meters of the original dam height. At the same time, due to the large original section of the earth dam, less earthwork and less work load, the labor force is easy to arrange and the rainy season construction impact is also small. This is a much faster and better construction measure, which can be promoted across the province. because
