Seismic Behavior of Underground Polymer Piping with Variable Interaction Coefficients

详细

The dependence of the coefficient of interaction between a polymer pipe and soil on soil moisture is determined experimentally. Variable coefficients corresponding to certain cases of moisture distribution are approximated. Based on variable coefficients, the longitudinal oscillations of underground polymer piping is studied in response to seismic loads. An algorithm and program were developed for calculating seismic stability.
