摘要
道路桥梁沉降段路基路面出现不均匀沉降问题,涉及地基承载力差异、填料性质变异以及荷载环境复杂等多重因素,主要表现为错台、开裂和局部凹陷等病害形式,这严重影响交通安全与道路使用功能。文章通过分析沉降段结构组成、空间界定和技术难点等工程特征,识别路基层面地基处理不足、路面层面承载能力局部差异及荷载环境季节性变化等关键成因,提出路基沉降防治技术、路面沉降防治技术和系统化监测预警技术这三大类综合防治措施,为沉降段工程质量控制与病害处治提供技术支撑。
The problem of uneven settlement of subgrade pavement in the settlement section of road and bridge involves multiple factors such as the difference of bearing capacity of the foundation.The variation of filler properties and the complex load environment is mainly manifested in the form of dislocation,cracking and local depression,which seriously affects traffic safety and road use function.By analyzing the engineering characteristics such as structural composition,spatial definition and technical difficulties of the settlement section,this paper identifies the key causes such as insufficient foundation treatment of the subgrade layer,the local difference of the bearing capacity of the pavement layer and the seasonal change of the load environment,and proposes three types of comprehensive prevention and control measures,namely subgrade subsidence prevention and control technology,pavement subsidence prevention and control technology and systematic monitoring and early warning technology,so as to provide technical support for the engineering quality control and disease treatment of the subsidence section.
