【摘要】 研制了一套能够在现场直接制取标准岩石力学实验原状样品的取样系统，并利用该取样系统，通过对从神华集团沙吉海煤矿现场制取的6种层理角度泥岩及煤岩原状试样分别在静态荷载、循环动荷载、不同加载速率、不同温度等条件下进行的一系列岩石力学实验，较全面研究了层理泥岩及煤岩在静态荷载及循环动荷载作用下力学特性及变形特性的层理结构效应，揭示了其力学及变形参数随层理倾角的变化规律；分析了循环卸载扰动后力学特性的变化特征及其动力学参数如滞回曲线、动弹性模量、动泊松比等的变化规律；最后对层理泥岩及煤岩在静态荷载及循环动荷载作用下的加载速率效应及温度效应进行了研究，揭示了其力学及变形参数随加载速率、温度及层理角度的变化规律。更多还原

【Abstract】 A set of sampling system was developed which can make standard undisturbed samples in thefield directly. A series of rock mechanics experiments are conducted under conditions of staticload, cyclic dynamic load, different loading rate, and different temperature etc. respectively for6bedding angles of undisturbed mudstone and coal samples which were made by using thesampling system from Shajihai coal mine. Bedding structure effect of mechanical properties anddeformation characteristics of mudstone and coal was studied comprehensively under static loadand cyclic dynamic load, and the variation regularity of the mechanics and deformationparameters with bedding angle was revealed. The changes of the mechanical properties after cyclicunloading disturbance and change regularity of kinetic parameters such as hysteresis curve,dynamic elastic modulus, and dynamic poisson’s ratio were analyzed. Finally, the loading rateeffect and temperature effect of mudstone and coal were studied under static load and cyclicdynamic load, and variation regularity of the mechanics and deformation parameters with loadingrate, temperature and bedding angle was revealed.更多还原
