摘要
以唐曹高速公路为研究对象,对建设阶段面临的欠固结路基施工稳定性进行研究.首先从路基的稳定系数、填料的性质、路基沉降、地基处理方法、滑移验算等方面,较为系统的分析了各因素对路基稳定的影响.分析过程中以实测数据为依据,并采用了数值模拟和理论分析相结合的方法.其次指出了建设中存在的潜在的不利因素.最后对不同因素引起的路基稳定问题,有针对性的提出了相应的解决方案,并对通车前、后公路的使用和监测提出建议.
Take Tang-Cao Expressway as the research object;analyze the stability of under-consolidated embankment during the construction.First systematic analyze influence of the various factors including stability coefficient,property of filler,subgrade settlement,method of foundation treatment,sliding checking etc.The analysis is based on the measured data,simulation and theoretical analysis are also included.Then point out the potential adverse factors.Finally give the corresponding solutions to different factors and suggestions for monitoring and using before and after completion.
