【摘要】 该文以上海浦东北路重车道路旧路面改建工程为例,介绍了土工格栅网的实际应用。原道路经2次开槽埋管,路面结构严重破坏。采用土工格栅网后,路面弯沉显著减小。通车半年多来,不存在明显的高程差,没有出现一条纵向反射裂缝。最后分析土工格栅网的作用机理,指出对其的使用必将是道路养护和改建工程中一种行之有效的手段。更多还原

【Abstract】 Taking the pavement reconstruction project of Shanghai Pu-dong-bei Rd for an example, the application of geotechnical grating network is introduced. The pavement structure of the road was seriously destroyed after the road had been cut for laying pipes twice. With the application of geotechnical grating network, the deflection of pavement is decreased distinctly, and there is no obvious height difference and longitudinal reflection crack after half a year’s operation. The functional mechanism of geotechnical grating network is analyzed finally.更多还原
