摘要
为解决既有公路拓宽改造工程中新旧路基不均匀沉降造成路面反射裂缝病害问题 ,研究了土工格栅对加强新帮填路基与既有路基的整体性以及提高地基的承载力和解决新旧路基不均匀沉降的问题 ,并对其加固机理。
In order to solve the the reflective cracks of pavement due to the uneven settlement between new and old subgrade in the road widening construction, the important role of geogrid on the whole stability and solving uneven settlement between new and old subgrade and improving load ability are studied The mechanism, construction technigues and the quality control of geogrid of road widening construction are analyzed
