公路大孔径钢波纹管通道变形分析

Deformation analysis of large aperture steel bellows channel in highway

针对大孔径钢波纹管通道顶部路面在运营阶段出现局部沉降的问题,通过长期现场监测,对钢波纹管通道的变形和其顶部路面沉降量进行分析。结果表明:钢波纹管通道未发现较大变形断面,已趋于稳定,后期不会产生大的变形,结构安全可靠;钢波纹管通道顶部路面存在沉降,有继续发展的趋势,施工时应严格按照规范要求进行,确保工程质量,以免后期产生较大变形及路面沉降。

In view of the local settlement of the road surface on the top of the large-aperture steel bellows channel during the operation stage,through long-term on-site monitoring,the deformation of the steel bellows channel and the settlement of the top road surface were analyzed.The results show that:the large deformation section has stabilized,and no large deformation will occur in the later period.The structure is safe and reliable;there is settlement on the top of the steel corrugated pipe channel,and there is a trend of continuous development.Therefore,the construction should be carried out in strict accordance with the specifications to ensure the quality of the project to avoid large deformation and road settlement in the later period.
