市政道路桥梁工程中沉降段路基路面的施工要点

Key Construction Points of Settlement Section Subgrade and Pavement in Municipal Road and Bridge Project

在当前的市政道路桥梁工程中,由于路面结构、路面压实、地基问题以及警示标识等问题的发生,很可能会造成路基路面的整体坍塌,在正式施工前,若不进行详细的实地勘察,很可能会因对场地的土质状况不了解而进行不科学的处理;最后导致路基路面的严重沉降。针对市政路桥工程沉降的危害及其原因进行分析,重点对沉降段路基路面施工技术的应用及优化措施进行探讨,以供参考。

In the current municipal road and bridge project,due to the occurrence of pavement structure,pavement compaction,foundation problems and warning signs,it is likely to cause the overall collapse of the subgrade and pavement.Prior to the formal construction,if the detailed field investigation is not carried out,it is likely to carry out unscientific treatment because of the ignorance of the soil condition at the site,finally leading to the serious settlement of the subgrade and pavement.This paper analyzes the hazards and causes of settlement in municipal road and bridge project,and investigates the application and optimization measures of subgrade and pavement construction technology in the settlement section,for reference.
