工程岩体力学参数确定方法的研究

A NEW WAY OF DETERMINING MECHANICAL PARAMETERS OF ENGINEERING ROCK MASSES

工程岩体力学参数的合理确定是多年来岩石力学界存在的一大难题。为解决该问题 ,根据何满潮教授提出的工程岩体的连续性理论 ,建立了工程岩体连续性的概化方法。该方法不仅适用于微观力学和细观力学介质的连续性判别 ,也适合于宏观工程岩体的连续性问题。在此基础上 ,提出了工程岩体力学参数确定方法 ,即根据室内完整岩块实验参数 ,结合野外工程岩体结构特点进行计算机数值模拟实验 ,从而确定工程岩体力学参数的新方法。所给出的正交节理化岩体的实验结果 ,展示了新理论。

A continuity model of engineering rock masses is built and the schematization method of engineering rock continuity reported. This method applies to the judgement of every kind of mechanics medium. On the basis of the method, a new way of determining the mechanical parameters of engineering rock masses is further presented. Numerical simulation is used here, combining the experimental parameters of intact rock with the structural properties of field rock. The experimental results of orthogonal jointed rock are given, and one bright future of application of this method to the engineering practice is demonstrated.
