结合裂缝计监测资料,通过建立数学模型对某碾压混凝土"金包银"坝型的常态混凝土与碾压混凝土结合部的裂缝进行定量分析,分析表明:该混凝土坝裂缝计实测资料能反映出坝体测点部位混凝土裂缝状况,其变化规律和分布规律符合该类型混凝土大坝的一般物理规律,运行期该类裂缝实测开度主要受上下游水压和温度的影响,时效分量已趋于稳定,坝体运行良好。
Based on monitoring data of crack meter, the joining position's crack between conventional concrete and RCC in "silver wrapped in gold "dam were analyzed quantitatively by establishing mathematical model. The result shows that the monitoring data of crack meter in the concrete dam can reflect the crack status. The rule of change and distributing accords with the ordinary physical rule of the type of concrete dam that the type of crack opening is mostly affected by upper and lower hydraulic pressure and temperature. Time weight has gone steady, the dam works normally.
