Abstract: Through analyzing the mechanism of treating differential settlement by geocell, the paper introduce the engineer case of treating the differential settlement by geocell for cut-fill section of Taigu highway. The result of plot detection and findings shows that modulus of resilience of subgrade reinforced by geocell is improved to be 1 times more, there is no mutation of the subgrade settlement at fill-cut connection, the settlement is transited gently, the maximum displacement has only 18mm.

摘要： 在分析土工格室处治路基不均匀沉降机理的基础上，介绍了应用土工格室柔性结构处治太古公路-半填半挖 路段不均匀沉降病害的工程实践。现场检测和长期观测结果表明:采用土工格室加固后的路基回弹模量提高一倍 以上，填挖交界处路基沉降无突变，呈平缓过渡形式，最大工后沉降仅18mm，说明该方法能有效地控制路基不均匀 沉降，处治效果较好。
