In order to accurately simulate the combined action of rainfall, high temperature and sunshine effect on asphalt mixture, the experiment of water-temperature-radiation circulation was designed. The changes of air void, split tensile strength, freeze-thaw splitting tensile strength and dynamic stability were quantitatively analyzed under the condition of different asphalt-aggregate ratio and different striking times during water-temperature-radiation cycle. Grey correlation analysis method was used to analyze the influence factors of the four parameters mentioned above, and comprehensive correlation was put forward to evaluate the influence factors of mechanical properties of asphalt mixture. It is proven that, the cycle index of water-temperature-radiation is the main factor. The striking times and asphalt-aggregate ratio influence mechanical properties of asphalt mixture less than the cycle index, and the initial void influences least.

China's electricity imports and its influence factors of ten years were analyzed. On this basis, the electricity imports and the influence factors of grey correlation were calculated by using grey correlation analysis method. It makes a conclusion that every influence factors effect on electricity imports, and establishes a grey model GM (1, n) of electricity imports as well as its influence factors and determines the quantitative relationship between the selected influence factors and electricity imported. The model has high accuracy, and meets the practical requirements, so that it makes a better load forecasting for our country and provides a theoretical basis for taking some electricity import measures.

Combining ideal solving method and Euclidean distance, the article constructs a new course evaluation model based on grey correlation analysis method. First, idealizes and standardizes the quantitatively treated evaluation indicators, constructs positive and negative incidence matrix. Then, defines grey correlation distance degree, puts forward an evaluation way close to the optimal solution and far from the worst one. At last, introduces the actual use of model by combining a course evaluation, and tests its accuracy and feasibility.

Construction formwork concrete shear wall is one of new type of structural system. In order to study the shear resistant strength of construction formwork concrete shear wall, 21 quasi-static test results were collected, influence factors which affect the shear resistant strength of construction formwork concrete shear wall through grey-correlation analysis method were analyzed. It is found that, among the influence factors, axial compressive force is the most important, secondly is the effective height of the wall, the distance among stiffening ribs in the latitudinal direction show small influence. And the expressions to estimate the shear resistant strength of construction formwork concrete shear wall were proposed by regression analysis method.

This paper presents the selection methods of typical substations based on grey correlation analysis method, and proposes classification principles of load characteristics. The actual example shows that using this method in process of statistical synthesis method modelling, the typical substations selected could be more representative, and the popularization and application of the modelling results are more accurate and effective.
