直方图法在工程地质勘察中的应用

Application of Histograms in Engineering Geological Survey

用直方图法进行数据整理 ,可从中找出试验数据的分布规律及质量状况。文章在介绍直方图作图步骤的基础上 ,以长沙市火星大道圭塘河大桥工程地质勘察的岩石试验结果为例 ,阐述了直方图法的应用。应用结果表明 ,将直方图法应用于勘察中 。

When histograms are used for data processing, it is possible to find distribution rules of the data and examine the data quality. This paper presents the drawing procedures of histograms and deals with the application of histograms, taking as a case study the test results of the rocks obtained during the engineering geological survey for the Guitang River Bridge on the Changsha Huoxing Road. The application shows that when histograms are used in survey, it is possible to evaluate the rationality of the layering and examine the quality of the samples based on the statistics of the test data.
