Abstract: FRPM pipe has the advantages of light weight, high strength, short construction period and good durability. It can be used as a substitute for traditional reinforced concrete road pipe culvert materials, and has a wider application prospect in highway engineering. In order to study the influence of the engineering transport vehicle during the construction period on the bearing characteristics of the buried glass fiber reinforced plastic pipe culvert and the thickness of the pipe top cover to ensure the safety of the pipe culvert, the dynamic load test and the load of the heavy soil are analyzed. The dynamic strain change characteristics of the glass fiber reinforced plastic sand pipe under driving are investigated. The results show that the top of the culvert pipe of the FRP sand pipe is the control point during construction, the maximum stress is 0.6 MPa, which is much smaller than the compressive strength of the pipe culvert. The thickness of the cover soil is 50 cm, which can allow heavy-duty engineering transport vehicles to pass, and the safety of the glass-reinforced plastic pipe culvert during highway construction. Sex control points have important guiding significance and engineering application value.
