摘要
针对新旧路基衔接处路基沉降不均匀对道路的影响,分析总结了路基加宽的方式及路基加宽结合处产生不均匀沉降的病害;研究了土工格栅在控制衔接处不均匀沉降的加固机理,并通过现场试验分析了其加固效果;提出了实际工程中新旧路基衔接处不均匀沉降的控制技术。
According to the influence of uneven settlement of the connection between new roadbed and old roadbed on the road, the roadbed widening patterns and uneven settlement diseases in roadbed connection were analyzed and summarized; the reinforcement mechanism of the geogrid in contorlling uneven settlement in roadbed connection was researched, and its reinforcement effect was analyzed through the field test. At last the uneven settlement controlling technology of the connection between new roadbed and old roadbed in the practical engineering was put forward.
