  地下工程混凝土结构为人们生活、出行带来诸多便利的同时，也存在一定的隐患。一旦火灾发生，由于高温造成混凝土产生热膨胀变形，产生热膨胀应力，影响结构的安全性与稳定性，对设备的正常运营与人员的生命安全造成威胁，因此，研究高温下混凝土的热膨胀系数具有重要的意义。\n

  该数据集基于中国科学院武汉岩土力学研究所自主研制的实时高温真三轴试验系统，考虑在0.5MPa三维应力和600℃范围内开展试验，选取了100、200、300和400温度水平进行试验，主要记录混凝土在三维应力状态下不同温度的三向线热膨胀应变。", "ds_source": "

 <p>&emsp;&emsp; The concrete structure of underground works brings many conveniences for people's life and travel, but it also has certain hidden dangers. In case of fire, due to the high temperature, the concrete will produce thermal expansion deformation and thermal expansion stress, which will affect the safety and stability of the structure and threaten the normal operation of equipment and the life safety of personnel. Therefore, it is of great significance to study the thermal expansion coefficient of concrete under high temperature.\n

   This data set is based on the real-time high temperature true triaxial test system independently developed by Wuhan Institute of Geotechnical Mechanics, Chinese Academy of Sciences. Considering that the test is carried out within the range of 0.5MPa three-dimensional stress and 600 ℃, 100, 200, 300 and 400 temperature levels are selected for the test, mainly recording the three-dimensional thermal expansion strain of concrete at different temperatures under the three-dimensional stress state.
