碾压混凝土筑坝技术已不再是单纯的施工工艺改革或填筑材料的研究,应该是移植土石坝的施工工艺来建造混凝土重力坝而派生的一种新坝型。该坝型扬弃了土石坝和混凝土重力坝的缺点,巧妙地综合了二者的优点于一体,是自身具有一系列基本特点和属性的新坝型。在枢纽布置、结构设计、计算方法、坝体细部设计、材料特性、施工工艺以及导流特性等各方面,都与常态混凝土重力坝存在差异。本讲就该坝型设计中的若干问题,作些简要论述。
RCC dam construction technology is no longer a simple reform of construction technology or filling materials research, should be the construction of earth-rock dam transplant technology to build concrete gravity dam derived from a new type of dam. The dam-type abandon the shortcomings of earth-rock dam and concrete gravity dam, cleverly combines the advantages of both in one, is itself a series of basic characteristics and properties of the new dam. There are differences with the normal concrete gravity dam in the aspects of hub layout, structure design, calculation method, dam body design, material characteristics, construction technology and diversion characteristics. This talk on the dam design of a number of issues, make some brief exposition.
