Abstract: This article carried out the indoor simulation experiments and analysis to study the force issues of the buried FRPM pipe under different loads. The tests acquired stresses and strains of the buried FRPM pipe in different parts, earth pressures and deformation characteristics of the pipe circumference at different locations, summarized the pipe-soil interaction law under different loads, as a basis for judging the force characters of the buried FRPM pipe in key parts, and provided a scientific basis for designing the buried FRPM pipe under loads

Key words: FRPM pipe, stress-strain characteristics, the pipe-soil interaction law, the force characters
