一、双铰拱坝的特点及目前设计中存在的问题近几年来,全国各地陆续修建了一些双铰拱坝,其规模也逐步有所发展,仅广西已建的就有和平、天生桥和白云江等。其中灵川县和平双铰拱坝已通过坝顶溢洪的考验;南丹县天生桥砌石双铰拱坝也已建成蓄水。在双铰拱坝由少到多由小到大的发展过程中,一方面以其工程量小的优点越来越引起了大家的兴趣和重视;同时,怎样使它的设计计算更完善、
I. Characteristics of Shuangjuan Arch Dam and Existing Problems in Design In recent years, several Shuangjuan arch dams have been built around the country, and their scale has also gradually been developed. Only Guangxi has built a complex system of peace, Tianshengqiao and Baiyun Jiang and so on. Lingchuan which peace double hinge arch dam has passed the test of overflow spillway; Nandan Tianshengqiao masonry double hinge arch dam has also built water storage. In the double hinge arch dam from less to more ascending to the development process, on the one hand the small amount of the advantages of more and more aroused everyone’s interest and attention; the same time, how to make it more perfect design calculations,
