摘要:
为解决公路用玻璃钢夹砂管管壁厚度设计缺乏标准与依据的问题，通过对玻璃钢夹砂管道试样进行压缩性能试验、拉伸性能试验获得不同管壁厚度的基本力学参数；结合在役玻璃钢夹砂管道的现场静载试验，得到在车辆荷载作用下玻璃钢夹砂管的变形规律，采用ABAQUS软件建立玻璃钢夹砂管道在车辆荷载作用下的数值分析模型，以路面基层材料劈裂强度值及管道最大允许变形量为控制指标，研究不同管道内径、不同管道埋深8种工况下玻璃钢夹砂管道的径厚比的最优取值。研究结果表明：管道的最优径厚比与管道内径及管道覆土深度有关，当管道内径为1.0 m，管道覆土深度分别为1、1.5、2 m时，管道的最优管壁厚度范围分别为20~25、25~30、32~37 mm，最优径厚比范围分别为40~50、33~40、27~31；当管道内径为1.5 m，管道覆土深度分别为1、1.5、2 m时，管道的最优管壁厚度范围分别为28~33、32~37、35~40 mm，最优径厚比范围分别为45~53、40~46、37~42；当管道内径为2.0 m，管道覆土深度分别为1.5、2 m时，管道的最优管壁厚度范围分别为35~40、40~45 mm，最优径厚比范围分别为50~57、37~44。在保证道路整体结构以及管涵自身结构安全的前提下，可根据管道内径以及管道覆土深度选择最经济的管壁厚度，从而节省管道原材料成本，减小玻璃钢夹砂管涵洞工程的造价。
Abstract:
In order to solve the problem of lacking the standard and basis for designing the wall thickness of glass fiber reinforced plastics mortar pipe for highway, the basic mechanical parameters of different pipe thickness were obtained through the compressive property test, tensile property test of pipe. Combined with inservice static load test of glass fiber reinforced plastics mortar pipe, the stress of pavement base and the deformation of pipe under the action of vehicle load were obtained. The numerical analysis model of glass fiber reinforced plastics mortar pipe under automotive load were established by ABAQUS software, the splitting strength value of the pavement base material and the maximum permissible deformation of the pipe were used as the control index, the optimal values of the ratio of pipe under nine different working conditions, including the inner diameter of pipe and the depth of buried pipe were studied. The results show that the optimal diameter to thickness ratio of pipe is related to the inner diameter of pipe and the soil depth of pipe. When the inner diameter of pipe is 1.0 m, the soil depth of buried pipe is 1, 1.5 and 2 m, the optimal wall thickness of pipe is20 to 25, 25 to 30 and 32 to 37 mm, and the optimum diameter to thickness ratio of pipe is 40 to 50, 33 to 40 and 27 to 31 respectively. When the inner diameter of pipe is 1.5 m, the soil depth of buried pipe is 1, 1.5 and 2 m, the optimal wall thickness of pipe is 28 to 33, 32 to 37 and 35 to 40 mm, and the optimum diameter to thickness ratio of pipe is 45 to 53, 40 to 46 and 37 to 42 respectively. When the inner diameter of pipe is 2.0 m, the soil depth of buried pipe is 1.5 or 2 m, the optimal wall thickness of pipe is 35 to 40 or 40 to 45 mm, and the optimum diameter to thickness ratio of pipe is 50 to 57 or 37 to 44. Under the premise of ensuring the overall structure of the load and the structural safety of the pipe itself, the most economical wall thickness can be selected according to the diameter of the pipe and the soil depth of the buried pipe, thereby saving the raw material cost of the pipe and reducing the cost of the culvert engineering of the glass fiber reinforced plastics mortar pipe. 6 tabs, 14 figs, 25 refs.
