The application discloses a test device and method for simulating the
impact effect of super-high-speed penetration into the ground, wherein a static load loading
system is used to apply static load to the periphery of a sample to simulate the ground stress environment, and a dynamic load loading
system is used to apply
impact dynamic load to the top of the sample to simulate the ground
impact, wherein in the dynamic load loading
system, a
phase change reaction kettle is used to heat liquid CO2 to a supercritical high-pressure state, a liquid charging module is used to charge the
phase change reaction kettle with liquid CO2, a
barrel is used to receive the high-pressure gas released by the
phase change reaction kettle and form an approximately planar ground
shock wave, a
stress wave lens module is used to adjust the width of the ground
shock wave through a
stress wave lens combination and act on the sample, and a control module can control the
peak pressure of the ground
shock wave by regulating the
heating power of the phase change reaction kettle and can control the duration of the ground shock wave by adjusting the aperture of the
barrel. The application realizes controllable and high-fidelity
simulation of the
impact effect of super-high-speed penetration into the ground.
