针对云南电力施工的特点,在云南省十六个州市对混凝土主要材料:水泥、砂、碎石进行取样,检测分析后运用“正交试验设计”对电力建设常用C15至C35混凝土配合比设计,制作立方体抗压试件。对试件进行超声回弹检测和抗压强度检测,对检测数据进行回归分析和曲线拟合,得到的回归方程更加适用于云南地区电力工程混凝土强度检测,精度更高,可以在实际工程中使用。
針對雲南電力施工的特點,在雲南省十六箇州市對混凝土主要材料:水泥、砂、碎石進行取樣,檢測分析後運用“正交試驗設計”對電力建設常用C15至C35混凝土配閤比設計,製作立方體抗壓試件。對試件進行超聲迴彈檢測和抗壓彊度檢測,對檢測數據進行迴歸分析和麯線擬閤,得到的迴歸方程更加適用于雲南地區電力工程混凝土彊度檢測,精度更高,可以在實際工程中使用。

After sampling ,testing and analysis of the major concrete materials such as cement ,sand and crushed stone in 16 prefectures and cities according to the electric power project construction features in Yunnan Province the cubic compression specimens were made for the common C 15 through C35 concrete mix design used in power construction by applying “the orthogonal experimental design” .Both the ultra-sonic rebound test and the compressive strength test were conducted on the specimens .The test data were regressively analyzed and the fitting curves were established ,the regress equation obtained from which is of high accuracy and is more applicable to the concrete strength test in power engineering projects in Yun-nan region .
