ABSTRACT

Rock engineering depends largely on the rock investigation and rock mechanics tests data. Therefore, the need to adopt integrated approaches to rock mechanics tests data management is more and more concerned. To facilitate sharing of rock mechanics tests data among different users more economically and efficiently, a standardized data model is needed to ensure the integrity and consistency of rock mechanics test data. This paper first reviews the achievements that have been made in rock mechanics tests data standards. Then based on the analysis of the data dependency relationships between the 52 ISRM Suggested Methods, a general rock mechanics test data model is proposed with the capability of describing rock materials, test preparation, and test procedures. Taking the Uniaxial Compressive Test as an example, the data structure of the test is given and represented in XML format. Finally, a rock mechanics test data management platform is established to provide a basis for the integration, sharing and application development of rock mechanics test data.
