The safety (stability) problem,ability of taking shear force,at the bottom pant of dam and within rock foundation usually happens in a RCC (roller compacted concrete) gravity dam over hundred meters (height). A structural improvement, integrated structure with artificial short joints to make a plan arch in the lower part of dam and decreased height of upper cantilever with inclined toward up stream bottom,was suggested. The new structure has been considered as the main type of high RCC dam located in middle southern China. The results of actual simulation calculation,creep stresses of accumulated temperature and self weight during construction, stresses of thermal drop and hydraulic pressure during operation,show the evidently advantages in stress-stability of the dam by improved measurements in structure mentioned above.

因坝高百米以上的碾压混凝土重力坝往往存在坝体下部抗剪能力和基岩内稳定安全度不足的问题,所以作者探讨一种结构改进措施:坝体下部采用不分永久性横缝只设人工短缝的整体式结构;坝体上部采用变高度分横缝的悬臂梁式结构。通过对我国中南地区某工程实例的仿真应力计算,即施工期的温度场和温度与累计自重徐变压力,运行期温度场和温差应力的计算,其结果表明,采用上述结构改进措施是有明显效果的。
