The newly formed land site has the characteristics of various degrees of compaction,uncompleted settlement under the self-weight and loose soil structure.This type of soils may cause some engineering hazards,such as a low bearing capacity,poor drivability of construction equipment on the land,out of alignment of newly installed pile head in this soil.In response to those issues,this paper presents a case history of the electronic information industrial park project near the Zhuhai west railway station.The design and construction method of the shallow improvement of the newly filled soil by in-situ solidification of forced mixing method is introduced.The construction process and the effect of the solidification soil are also analyzed.The re-sults show that the bearing capacity of the in-situ solidification soil is significantly improved,the superficial hard crust by the in-situ improvement is formed quickly to accommodate construction equipment and solve the problem of the misaligned of pile head.
