摘要
通过对不同强度等级的高性能混凝土试件进行抗压强度与回弹试验,根据最小二乘法原理,对混凝土强度和回弹试验数据进行回归和统计分析,建立了承秦高速公路高性能混凝土回弹法专用测强曲线方程,为本工程混凝土强度质量检测评定提供了可靠的推定依据。
Upon the basis of putting high-performance concrete test blocks of different grades of strength to compression-strength tests and rebounding tests,the data on the strength of concrete and the resilience tests are regressively and statistically analyzed by means of the least square method,with the special resilience-method-based strength-testing curves for the high-performance concrete of the Chengde-Qinhuangdao Expressway established,which provide reliable inferential grounds for the evaluation of the strength quality of the concrete used for this project.
