摘要

本研究评估土工格室加筋边坡的性能。采用有限差分软件FLAC3D对土体和土工格室的弹塑性特性进行了三维模拟。为了研究土工格室的加固效果,将土工格室孔径大小、厚度、土工格室布置条件和土壤压实度作为可变参数。并对土工格室配筋体系与传统平面配筋体系进行了比较。结果表明,土袋尺寸、厚度和土压实度对土工格室加固边坡的性能有较大影响。此外,发现临界滑动面以第一格室加固为界,并通过增加格室层之间的垂直间距来增加边坡的稳定性。此外,土工格室加固与土工格栅加固的对比表明了采用蜂窝蜂窝土工合成加固的有效性。

Numerical investigation of geocell reinforced slopes behaviorby considering geocell geometry effect
The present study evaluates geocell reinforced slope behavior. A three dimensional analysis is carried out to simulate soil and geocell elastoplastic behavior using the finite difference software FLAC3D. In order to investigate the geocell reinforcement effect, the geocell aperture size, thickness, geocell placement condition and soil compaction had been considered as variable parameters. Moreover, a comparison is evaluated between geocell reinforcing system and conventional planar reinforcement. The obtained results showed that the pocket size, thickness and soil compaction have considerable influence on the geocell reinforcement slope performance. Moreover, it was found that the critical sliding surface was bounded by the first geocell reinforcement and the slope stability increases, by increasing the vertical space between geocell layers. In addition, the comparison between geocell and geogrid reinforcement indicates the efficiency of using cellular honeycomb geosynthetic reinforcement.
