桥涵台背回填施工控制研究

Analysis for Settlement of Bridge Abutment Backfill

桥涵台背回填土体在使用期内的沉降主要由地基沉降和路堤沉降两部分组成,这一问题存在于大多数工程之中。它的产生不仅增加了桥涵和路面的养护费用,也给正常的交通运输工作带来了不便,同时还给国家和社会带来了重大的损失和恶劣的影响。通过对路堤与地基的沉降原因进行分析,提出了一系列的控制措施来控制玉林至铁山港高速公路第三合同段的桥涵台背回填,这些控制措施可以为今为类似工程的施工提供相应的指导。

The settlement of bridge abutment backfill is mostly consisted of the settlement of foundation and embankment in the period of use.The problem exists in many construction projects.It not only badly increases bridge maintenance cost,but also has disadvantageous effect on the work of normal transportation.It brings significant loss to the country and has negative influence on the society.This paper provides a series of control measures by analyzing the reasons of settlement in foundation and embankment.The methods can be provided as guidance for engineering construction and detection in future.
