A hypergravity model test device for simulating a progressive failure of a shield tunnel face, including a model box, a shield tunnel model, a servo loading control system and a data acquisition system. The servo loading control system includes a servo motor, a planetary roller screw electric cylinder and a loading rod. The data acquisition system includes a displacement transducer, an axial force meter, a pore pressure transducer, an earth pressure transducer and an industrial camera. The servo loading control system is connected to an excavation plate through the loading rod to control the excavation plate to move back and forth along an axial direction of the shield tunnel model at a set speed to simulate failure of the shield tunnel face. A method for simulating a progressive failure of a shield tunnel face is also provided.

An electromagnetic field generating apparatus for treating pathological cells, in particular with tumor suppression function. The ratio of static magnetic field to alternating magnetic field is in the range of 0.5-2.5, and the total intensity is in the range up to 100 mT. It provides non-invasive low toxicity and side effects, significantly inhibiting a plurality of tumors, influencing the intracellular superoxide radical content, and promoting cell autophagy. The mechanism of action of the magnetic field is on the electron spin energy levels and consequently on free radical concentration. Additional magnetic field having frequency up to 100 MHz and intensity down to microTesla range can be also used to improve the antitumor efficacy in combination with the static as well as the extremely low frequency electromagnetic field (1-300 Hz) influencing the spin hyperfine resonance. A combination method is also provided of a power-frequency electromagnetic field generating device and a platinum-based medicine.
