道路桥梁工程中沉降段路基路面施工要点分析

Analysis on Key Points of Subgrade and Pavement Construction in Settlement Section of Road and Bridge Engineering

文章首先阐述道路桥梁工程路基路面的沉降危害,然后分析导致路桥沉降区域路基路面出现不均匀沉降的原因,指出路桥工程结构设计不科学、施工材料不合格、搭板沉降是主要原因,最后结合沉降原因,从搭板设置、地基处理、选择台背填料、路面路基施工方面对施工要点进行梳理,以保障路桥工程质量,实现预防公路桥头跳车和延长路桥工程使用寿命的目标。

This paper first expounds the settlement hazards of subgrade and pavement in road and bridge engineering, then analyzes the causes of uneven settlement of subgrade and pavement in the settlement area of roads and bridges, and points out that the unscientific structural design, unqualified construction materials and approach slab settlement of road and bridge engineering are the main causes. Finally,combined with the causes of settlement, the key construction points are sorted out from the aspects of approach slab setting, foundation treatment, selection of abutment back filler, and pavement and subgrade construction, so as to ensure the quality of road and bridge engineering and achieve the goal of preventing highway bridgehead bump and prolonging the service life of road and bridge engineering.
