The structural characteristics of 1,2,4-triazole with high nitrogen content will cause it to the release of a large amount of gas when it occurs pyrolysis, which may have a certain impact on industrial production safety. In the industrial process, there will be some other impurities mixed into it, so the influence of these impurities on the 1,2,4-triazole pyrolysis gas is worth exploring. In this study, the adiabatic acceleration calorimeter was used to simulate the adiabatic conditions to study the pressure value of the gas generated by the pyrolysis of 1,2,4-triazole itself, and the influence of the addition of three basic impurities on the overall pyrolysis pressure value. Experiments show that these three impurities can affect the pressure value of pyrolysis gas in different degrees.

Therefore, accurately understanding the dynamic changes in the infiltration characteristics of embankments is of great significance for judging and evaluating the stability of engineering. This study conducted indoor model experiments and used ground penetrating radar to detect the phreatic lines of soil. By comparing the radar detection results with the measured position of the phreatic lines, it was determined that the phreatic lines appeared as a continuous strong reflection surface with similar shapes in the radargram, and the reflection below the reflection surface became weaker. Through time-domain analysis of the single waveform at different time points, it was found that the amplitude of the reflected wave at the saturation line was larger, and the energy attenuation below the saturation line was faster, resulting in a rapid decrease in amplitude; perform Fourier transform on a single channel signal to obtain a spectrogram, and perform frequency domain analysis on it.
