溪柄碾压混凝土薄拱坝根据施工期至运行期的温度场和累计组合应力场的仿真计算进行结构设计,用混凝土多轴强度及实验韧性判别,对施工期和运行期用不同安全系数,采用低绝热温升(12℃)混凝土,拱坝中设人工短缝以改进整体式碾压混凝土结构的应力和传力方向,63.5m高的拱坝仅用半年即完成整体碾压工作并勿需等待冷却和灌浆即可蓄水,提前发挥工程效益。
The structural design of Xishuang RCC arch dam is carried out according to the temperature field during construction period and operation period and the cumulative combined stress field. The multi-axial strength and the experimental toughness of concrete are used to identify the structure. During the construction period and operation period, different safety factors, Using low adiabatic temperature rise (12 ℃) concrete, arch dam artificial short stitches to improve the integral RCC structure of the stress and force direction, 63.5m high arch dam in just half a year to complete the rolling work and Do not wait for cooling and grouting can be impounding, advance engineering benefits.
