| 摘 要： | 根据地下工程岩体开挖失稳的特点，通过室内对辉绿岩在不同的围压下的加卸载试验，研究了辉绿岩在不同的加卸载路径下的力学特性；并采用能量理论、损伤力学的观点对室内试验的岩体破坏的力学特性进行了分析，得到了岩样在加卸条件下岩体的变形特征、岩体损伤演化过程、不同路径下的岩体强度等特性，并对不同路径的力学特性、力学参数和破坏机理进行了对比分析。根据试验结果表明：采用卸载的方式获得的岩体力学参数更接近于地下工程的开挖实际。

| Abstract: | In order to study the rock mechanical properties of underground engineering are closely linked to the mechanical properties after failure,based on the results of the loading and unloading experiments of diabse on the three press,firstly the mechanics characteristics of the loading and unloading of rock mass were studied,and the testing results of unloading mechanics parameters were obtained.Taking the ideas and methods of loading and unloading rock mass mechanics,the results of mechanical properties of rock... |
