According to the force-heat-chemical multi-field coupling loading system and the loading test method, the test temperature is controlled through the vertical tube furnace, the partial pressure proportion adjustment of the chemical reactant concentration is realized by controlling the input flow of the reactant gas in the quartz furnace tube, and the constant force or constant displacement load loading in the stretching direction is realized through the sample loading system; and finally, real-time adjustment of mechanical, thermal and chemical field variables is realized. 本发明提出力-热-化多场耦合加载系统及加载试验方法，通过立式管式炉控制试验温度，通过控制石英炉管内反应物气体的输入流量实现化学反应物浓度的分压比例调节，通过试样加载系统实现拉伸方向的恒力或恒位移载荷加载，最终实现对力学、热学和化学场变量的实时调节。
