The objective of this paper is to give a comprehensive review of the status quo and future trends of digitization in rock mechanics and rock engineering. Research topics essential to the process of digitization are firstly discussed, including data acquisition, data standardization, geological modeling, visualization and digital-numerical integration. New techniques that will play an important role in digitization process but require further improvement are then briefly proposed. Finally, achievements of present methods and techniques for digitization in substantial rock mechanics and rock engineering are presented.展开更多

Moreover, over the years, I have enjoyed looking through the issues of the existing Chinese Journal of Rock Mechanics and Engineering （CJRME）. The content of this Journal, initiated in 1982, is partially accessible to foreigners because the Contents, paper Abstracts and Figure captions are published in English. The number of rock mechanics articles in each monthly issue of the Journal is far more than any other country can produce. This activity is also reflected in the fact that China now has more ISRM members （502） than any other country -- and the number is no doubt continuing to grow! Furthermore, the Editor-in-Chief of the CJRME, Professor Feng Xiating, will be the next ISRM President for the period 2011-2015.展开更多

School of Information Science ＆ Engineering, Northeast University, Shenyang 110004, China）Abstract： A main characteristic of the reconfigurable mobile robot AMOEBA-1 is that it has diverse configurations, but some reconfigurations are difficult to realize under the influence of ground conditions. A cooperative reconfiguration method is proposed to reduce reconfiguration resistance and enhance the adaptability of the robot to the environment. The mathematical model is established correspondingly. The kinematics and mechanical properties of each section of the robot are analyzed. A part of resistance is transformed into active force of reconfiguration, and transforms are actualized among five specific configurations. Further, the linearization of model based on a perturbation analysis method is used to reduce the computational complexity. Finally, an evaluation criterion is proposed for AMOEBA-I＇s cooperative reconfiguration performance. The validity of the cooperative reconfiguration method is proved by simulations and experiments.展开更多
