本文利用钻芯法、超声法、超声回弹综合法等测试手段,对佛子岭大坝混凝土耐久性指标、坝体缺陷进行了较为全面的检测与评价.同时建立了混凝土抗压强度与28天预留试块强度、劈裂抗拉强度、轴心抗拉强度、静动弹性模量之间的相关公式及综合法测强专用曲线.并对坝体裂缝、伸缩缝灌浆效果及其对结构整体性的影响进行了分析与评估.测试结果为设计和坝体缺陷处理提供了依据.
In this paper, we use the core drilling method, ultrasonic method and ultrasonic rebound method to test the concrete durability index and the dam defect of Foziling Dam.At the same time, the compressive strength between concrete and 28 Day reserve the strength of the test block, splitting tensile strength, axial tensile strength, elastic modulus of static and dynamic correlation between the formula and the special test strength curve. And the dam cracks, expansion joints grouting effect and its Structural integrity of the impact of the analysis and evaluation.The test results provide a basis for the design and dam defect treatment.
