三轴压应力下声发射的震源分布和震源机制(1)——实验设备和震源分布——出原理佐藤隆司西泽修楠濑勤一郎在油压式三轴压缩岩石破裂试验中,为了得到声发射的波形,必须把连接贴在试件上的传感器和测定器的同轴线从围压容器内向外引出。同时,为了精确测定声发射的震源,还需要许多传感器,并且要有在不漏油的条件下取出同轴线的技术。一般说来,这样的取出口,要在取出口附近把各条屏蔽线汇集在一起,并与围压容器共同接地,但这种方法有产生感应
Source distribution and source mechanism of acoustic emission under triaxial compressive stress (1) - Experimental equipment and source distribution - Outgoing principle SATO Takashi Nishizawa Kusanichiro In a hydraulic triaxial compression rock failure test, in order to obtain Acoustic emission waveform, the connection must be attached to the specimen on the coaxial cable and measuring device from the confining pressure container to the outside leads. At the same time, many sensors are needed to accurately determine the source of acoustic emissions, and there are techniques to remove the coaxial line without oil leakage. In general, such a take-off port, in the vicinity of the take-off to the shielded wire together together, and with the co-pressure container grounding, but this method has induction
