| 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.

Application of treating differential settlement of subgrade by geocell at Taigu highway |
| |
| 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. All these proved that the method is effective for treating the differential settlement of subgrade and treating effect is satisfying. |
