摘　　要：交椅湾板块道路建设用地广泛分布着滨海相软土,为正常固结或欠固结的饱和软土,具有孔隙比大、渗透性差、含水量高、天然强度低、压缩性高等特点。交椅湾板块“五纵一横”道路建成通车后,均出现了一些道路不均匀沉降及裂缝现象,影响了道路的美观以及使用功能。以东莞滨海湾新区交椅湾板块已完工的“五纵一横”市政道路工程为研究对象,采用现场调研、理论计算、有限元计算的方法,对交椅湾板块市政道路路面不均匀沉降问题、道路出现病害的原因进行研究分析,并提出相应的工程对策,这对滨海湾新区后续道路的工程建设具有重要的意义。The road construction land of Jiaoyiwan plate is widely distributed with coastal soft soil,which is normally consolidated or underconsolidated saturated soft soil,and is characterized by large void ratio,poor permeability,high water content,low natural strength,and high compressibility.After the completion and opening of the"Five Verticals and One Horizontal"road in the Jiaoyi Bay area,there have been some uneven settlement and cracks on the road,which have affected the aesthetics and functionality of the road.Taking the"five vertical and one horizontal"municipal road project completed in Jiaoyiwan Block of Dongguan Binhai Bay New Area as the research object,uses the methods of field investigation,theoretical calculation and finite Metacomputing to study and analyze the uneven settlement of municipal road pavement in Jiaoyiwan Block and the causes of road diseases,and puts forward corresponding engineering countermeasures,which is of great significance to the follow-up road construction of Binhai Bay New Area.
