摘要
珠海机场的站坪区，地面以下约１０ｍ存在淤泥层，且分布不均，可能产生不利沉降，需要进行处理。设计部门要求处理后的剩余沉降量不大于５０ｍｍ。采用堆载预压进行处理。为了加速预压的压缩过程，除超载预压外，还设置了水平排水和竖向排水。处理过程中进行了总沉降和分层沉降以及水平位移的观测。处理是成功的：实测剩余沉降不大于１０ｍｍ。
Ten meters below the ground at the park of Zhuhai airport there is a silt layer of nonuniform distribution.It could cause unfavourable ground settlement,and treatment works are required. Not more than 50 mm of residual ground settlement after treatment is specified by the design department.The loadprepressed method is adopted to treat it.In order to speed the silt layer's compressive process caused by prepressing,besides taking overload prepressing measure,the horizontal and vertical drainages are also arranged. During treatment,the total and stratified settlements and horizontal displacements of strata in the park area are observed.The recorded residual ground settlement is not more than 10 mm,which shows the successful treatment works.
