摘要
以工程实测数据资料为基础,从管道铺设开挖沟槽卸土回弹后在回填土体自重压力下的再压缩,围护桩体打、拔扰动造成的管道周边及基础土体损失,管道上部回填料松散引起的自密实压缩变形等几方面原因,对软土地基场地条件下铺设的市政排水管道工后沉降原因进行了详细分析,并提出了减少排水管道工后沉降的相应对策。
Based on the measured data of the project, the article analyzes the settlement causes of municipal drainage pipe laid in soft subgrade after construction from the aspects of the re-compression of rebounded trench bottom soil in gravity load of backfilling, the soil losing surrounding the pipe and foundation caused by the inserting and pulling of enclose piles, and the self-compacting compression deformation caused by loose backfilling material above pipe, and puts forward the relative countermeasures to decrease the settlement of drainage pipe after construction.
