摘要
针对胶凝砂砾石坝内部存在的缺陷问题,以混凝土抗压强度试件为对象,采用数值模拟的方法,分析了在不同缺陷状态下混凝土试件抗压强度的衰减,结果表明,内部缺陷对混凝土抗压强度的影响是不可忽视的。将试验数据作为随机事件的一个样本,借助数值模拟的方法是探究解决胶凝砂砾石坝内部缺陷影响强度问题的途径之一。
Aiming at internal defects of cementitious gravel dam issue, taking concrete test pieces as specimens to test compressive strength, this paper analyzes the attenuation of compressive strength of concrete specimens under different defect state by numerical simulation methods. The results show that the influence of internal defects on concrete compressive strength should not be ignored. Taking the test data as a sample of random events, the numer- ical simulation finds itself one of the solutions to explore the method of resolving the impact of internal defects on the compressive strength of cementitious gravel dam.
