摘要
基于土工格室的特殊力学性能,利用其加固沙漠路基。采用Duncan-Chang双曲线模型、Biot固结理论对土工格室加固沙漠路基的机理进行理论研究,并铺筑了野外试验路对理论分析结果验证。结果表明,土工格室对提高沙基承载能力和抗剪能力效果非常明显,能达到减薄路面结构层的目的。
Based on geocell＇s mechanic performance, geocell is applied to strengthen expressway subgrade in desert. The strengthening mechanical mechanism is studied with Duncan-Chang hyperbolic model and Biot consolidation theory. A test road is constructed to verify the analysis resuits. The results show that geocell can raise subgrade＇s bearing capacity and anti-shear evidently, so the thickness of pavement structure can be reduced. 4 tabs, 5 figs, 7 refs.
