| 摘 要： | 南丹县拉希双层拱坝是一项加固扩建工程。已建砌石拱坝坝高３７．７５米，有效库容７３７万立方米，计划将坝加高到５５．２米，有效库容增至２７５５万立方米，初拟在原坝上加高，但新旧坝体结合，应力分析和基础处理等均感困难，故改用在上游另建一高为５５．２米的薄拱坝与原拱坝形成双层拱坝联合受力的方案。两层拱坝间充水，传递部分水压力。这样不仅解决了上述难题，还改善了坝肩稳定条件和坝体应力状况，节省了工程投资。工程现已投入运行。

| Abstract: | The double deck arch dam of laxi reservoir in Nandan county is a reinforcing and extending project. Original arch dam is 37. 75m high. The dam was planned to heightem to 55. 2m,finally a new thin arch dam of 55. Zm high was built upstrea the old one instead. Both the old and the new form a double deck arch dam and support loads. The space between two dams may be filled with water,So a part of water pressure is transmitted,and the dam abutment steady and the stress state are improved. |
