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20~1 200℃下的岩石的热膨胀应力。
The structure and design process of rock high temperature axial stress testing device designed and developed by ourselves are introduced. The stress testing device is designed to study the stress-strain relationship of surrounding rock of coal underground gasifier at high temperature. It can test the thermal expansion stress of rock at 20-1 200 ℃.
