Glass fiber reinforced plastic mortar pipes is a new type of composite material. In order to obtain the design and construction parameters and to detect the cracking reason for the glass fiber reinforced plastic mortar pipes (FRPM) culvert with high filling, model test on mechanical properties of FRPM culvert was performed. The results show that the deformation laws of circumferential tension or compression are consistent, with the increase of filling height, the growth of stress in FRPM and vertical soil pressure are nonlinear. Simulation of the maximum filling height of 12m, under axial loading, the circumferential stress and strain values of culvert are 6770kPa and 2109 (ε)/(×10) ; the maximum soil pressure occurred at the top of the culvert, the value is 322kPa ; under eccentric loading, the maximum values of circumferential stresses and strain are 6092kPa and 1898(ε)/(×10); the maximum value of soil pressure is183kPa.
