宁靖盐高速公路X标段软基处理及工后沉降观测与分析

The Xrd Contract Section of Soft Foundation Treatment,the Settlement Observation and Analysis after Working in Ningjingyan Highway

主要介绍宁靖盐高速公路X标段 (k1 38+ 0 0 0～k1 5 3+ 0 0 0 )工程地质概况、软基设计、施工方案以及沉降观测情况 ,选取了代表性的桥头 1 0m、桥头 5 0m、圆管涵、箱涵处作为沉降观测点进行软基的沉降观测 ,并对本段高速公路通车运营近两年的动态沉降观测资料进行了分析 ,得出了具有一定参考价值的结论 ,在此基础上对累计沉降量和沉降曲线进行研究 。

This paper briefly present that engineering geology summary, soft foundation ,the project of construction and settlement observation of the Xrd(k138+000~k153+000) contract section . It select some representative settlement observation point locations ,such as the distance 10m from the end of bridge , the distance 50m from the end of bridge ,pipe thrusting, trunk culvent. It analyze the dynamic settlement observation data of two years working after the highway is transported, some reference conclusions are put forward , on the basis of analysis ,the accumulated settlement and settlement curve is researched ,the result of soft foundation treatment is appraised.
