| 摘 要： | 针对江苏沿海某高速公路沿线的工程地质情况,结合建设和营运过程中长时间的现场沉降观测数据,总结了江苏海相软土地区水泥土搅拌桩复合地基和未进行深层处理的地基沉降变形特性,通过比较得出两类不同地基处理方法在不同阶段沉降发展过程有所不同。对施工期和营运期的沉降进行了统计,得出路面施工期与两年营运期的沉降具有较高的相关性,营运期第二年的沉降约为第一年的一半;同时对不同处理方法的沉降稳定时间进行了汇总分析,结果表明沉降控制标准的确定应结合不同的地基处理方法。

| Abstract: | With the engineering geology conditions of a coastal expressway,the deformation characteristics,of both no deeply-settled foundation in soft Marine clay and cement mixed piles composite foundation,are summarized by long term observation during construction and operation period.Based on a great deal of monitoring data,a conclusion is drawn that the development process of settlement of the two foundation treatment methods differ in the different periods of construction and operation.By comparing the settlemen... |
