overflow section meaning in Chinese

溢流段
溢流截面

5 . based on longtan project , temperature control and crack prevention of a typical overflow section block of the high rcc gravity dam is studied as a case study
以“十?五”国家电力公司科技攻关项目为背景，深入系统地进行了龙滩高碾压混凝土重力坝典型溢流坝段的温控防裂研究。
According to differences of construction process , boundary condition , temperature and stress of two schemes extending 3m deep short seam on upstream face in the middle of rcc overflow section and no short seam are calculated , what " s more , in this paper the equivalent line drawing of stable temperature field and unstable temperature field during construction and operation period and the duration curve drawing of typical points " s temperature and stress are plotted , and the results of peak and minimum on temperature in every month and maximum on tensile stress are attained
根据施工过程和边界条件，对溢流坝段中间上游面增设3m深短缝和不设短缝两个方案进行了温度和应力计算，并绘制出稳定温度场等值线图及施工期、运行期非稳定温度场等值线图，典型点温度和应力历时曲线图，逐月最高、最低温度和最大拉应力及相应位置等成果。
