碾压混凝土技术在重力坝施工中的广泛应用促使拱坝的支持者寻求各种方法来运用这一先进技术。本文介绍改进拱坝的结构和施工技术的两种方法。为便于碾压混凝土技术的实施，有必要开发特殊结构的拱坝。笔者提出了两种适用于碾压混凝土的拱坝结构。除了技术问题外，本文还考虑了应力应变状态的形成过程和拱坝的费用估算等问题。
The widespread use of RCC technology in gravity dam construction has prompted proponents of arch dams to find ways to apply this advanced technology. This article describes two ways to improve arch dam structure and construction techniques. In order to facilitate the implementation of RCC technology, it is necessary to develop arch dam with special structure. The author put forward two kinds of arch dam structures suitable for roller compacted concrete. In addition to the technical problems, this paper also considered the formation of stress-strain state and the cost estimation of arch dam.
