摘要
结合山区公路改扩建工程,指出山区高填方新旧路堤容易出现不均匀沉降等问题,根据数值分析结果和现场实际情况,提出采取土工格室处理方案,重点分析了现场施工控制方法与检测标准,并进行了现场新旧路堤搭接段深层侧向位移和沉降观测数据分析。结果表明,严格控制现场施工质量,可保证土工格室所在结构层发挥立体加筋效果,有助于提高新旧路堤的搭接稳定性,降低新旧路堤的不均匀沉降。
In mountain highway widening projects,it is easy to appear differential settlement problem for the mountain high fill new-old embankment.According to the numerical analysis results and field condition,the geocell treatment plan is proposed.Then the field construction control method and the examination standard are analyzed in detail.At the same time,the in-depth lateral displacement and settlement observation of the field new-old embankment joining sections are analyzed.The results show that the strict controlling field construction quality,which may guarantee the geocell structure layers to have a three-dimensional reinforcement effect,is helpful to enhance the stability of new-old embankment joining sections,and reduce the differential settlement.
