北京某高填方高速公路路基沉降变形规律研究
摘要:公路建设中高填方所带来的路基沉降问题是引起桥头跳车等多种公路建设质量通病的诱发因素。很多工程项目或项目部分区段由于受建设工期短、无预压周期等建设条件所限,必须在有限时间内完成高填方路基的施工和运营,因此有效控制和预测高填方路基在施工阶段以及运营阶段的沉降变形,为采取合理的工程措施控制路基沉降引起的各种质量问题具有重要的理论和工程实际意义。依托某高速公路高填方路基工程,首次系统研究了北京地区不同地基类型和施工工艺下高填方路基的沉降变形规律,有效指导北京地区高填方路基设计、施工和运营期养护。
Abstract:The settlement of high filling subgrade is one of the major factors end to some highway diseases,such as vehicle bump approaching bridge,different deformation,crack and so on.Limited by short construction period and not preloading conditions,high attention must be paid to controlling filling progress and settlement characters of subgrade.Effective measurements are taken to control some engineering problems,resulting from settlement of high filling subgrade,during highway construction and operation.Taking one highway in Beijing for example,some features of settlement and deformation of the high filling subgrade are discussed due to different foundation nature,engineering geology,and construction method in this paper.The results will offer directly scientific basis for decision of design,construction and operation of the highway.
