摘　　要：在对碾压混凝土拱坝理论基础研究的基础上,提出了碾压混凝土拱坝仿真设计新思想,并通过科研和设计成功修建了两座碾压混凝土拱坝,即福建溪柄碾压混凝土薄拱坝和新疆石门子碾压混凝土拱坝,提出人工短缝新结构以释放应力,铰结拱新结构提前蓄水和柔性拱新结构使坝体和基础变位协调而应力不恶化等新结构形式,并经过工程验证了新结构的合理性。Based on many years of studies on RCC arch clam construction, new method of simulating design is proposed. After successful design and construction of two RCC dams-Xibing in Fujian and Shimengzi in Xingjiang, new structures of artificial short-crack for releasing stress, hinged arch for early storage and flexible arch for displacement of dam and embankment without worse of stress are adopted and approved to be feasible.
