    摘要:

    首先讨论了岩石动态复合型初始断裂实验的试件设计问题,指出四点弯曲试件是非常理想的试件;其次论述了大理岩动态四点弯曲试验的试验方法,并进行了初步的试验研究,得到了有实际意义的断裂曲线。

    Abstract:

    This paper discusses the specimen design in experiments of dynamic mixed-mode fracture initiation in rock, and explains that four-point bending specimen is very adapted;then it discusses the experimental method of four-point bending specimen,and an initial experiment and analysis was carried out. Some meaningful fracture curves were obtained.
