摘要
介绍了自行设计研制的岩石高温轴向应力测试装置的结构、设计过程.该应力测试装置是为研究煤炭地下气化炉围岩在高温下应力应变关系而设计的,它能测试20～1200℃下的岩石的热膨胀应力.
In this paper, a high temperature axial stress testing apparatus is designed and the structure of it is introduced. It can measure the stress of rock under the temperature between 200℃ to 1200℃. Its structure is very simple, and has steady behavior. Its sensitivity is good enough to be used in experimental study.
