摘要: 玻璃钢夹砂管具有轻质高强、施工工期短、耐久性能好等优势,可作为替代传统钢筋混凝土的公路管涵材料,在公路工程上应用前景广阔。为研究公路施工期间工程运输车行驶状态下对埋地玻璃钢夹砂管涵洞受力特征的影响,确保管涵安全的覆土厚度,通过设计现场动载试验,分析不同覆土厚度和重车荷载行驶下玻璃钢夹砂管的力学性能。结果表明,施工期玻璃钢夹砂管涵洞管顶为控制点,最大应力为0.6 MPa,远小于管涵抗压强度,覆土厚度为50 cm时可允许重型工程运输车通行。本文研究对公路施工期间玻璃钢夹砂管涵洞安全性控制点具有重要的指导意义与工程推广应用价值。

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.
