复合材料路面器材承载特性数值仿真分析

Numerical Simulation Analysis of Complex Fiber Reinforced Plastics Pavement Equipment’s Bearing Characteristics

以带增强杆的复合材料路面器材为研究对象，基于数值仿真技术分析了淤泥质土、软弱粘土、砂土3种典型松软地面下该路面器材的沉降特性；以温克尔（E．Winkler）地基模型为基础，定量确定了路面器材各参数对路面沉降的影响。研究结果表明，地基反应模量、路面器材的杆间距、杆直径都对复合材料路面沉降有显著影响，通过调整这些因素可以提高复合材料路面器材的承载能力。

This paper took the complex fiber reinforced plastics （FRP） pavement-equipment as the research object, and an- alyzed the pavement-equipment＂ s settlement characteristics at three typical soft ground of mucky soil, soft clsy and sand on the basis of numerical simulation technology. Based on E. Winkler foundation model, the FRP pavement-equipment param- eter＇s influence on the settlement of the ground was quantitatively determined. The result shows that foundational response modulus, spacing and diameter of the pole produce remarkable influence on the settlement of the complex fiber reinforced plastics pavement-equipment. By adjusting these factors ,we can promote the bearing capacity of the pavement-equipment.
