摘要
根据工程地质勘察报告,某人工岛的施工区域内有淤泥质黏土、黏土、粉质黏土等软弱土质,且围堤堤身较高,工期紧,围堤和吹填施工速度快,施工速度不均匀,所以有必要对围堤地基和吹填区进行施工观测。工程通过分层沉降、深层位移、孔隙水压力等施工监测方法来指导和控制施工,有效预防地基和堤身发生滑动或产生过大位移变形,确保施工安全和使用要求。监测数据分析为类似工程提供了参考。
according to the geologic survey report, the engineering area of an artificial island is characterized by weak soil such as silty clay, clay and silty clay, high dike, tight time schedule, fast construction of embankment and reclamation, as well as ununiform construction speed, so it is necessary to carry out construction monitoring for dike foundation and dredger fill area. The construction is guided and controlled by layered settlement, deep displacement, pore water pressure and other construction monitoring methods, which effectively prevent foundation slide or large displacement, thus ensure the safety of construction and meet the requirement for use. The analysis of monitoring data may serve as reference for similar works.
