在标准化佛山市所有钻孔资料的基础上,应用GMS软件构建了佛山市第四系软土空间格架,并基于太沙基渗流固结理论采用分层总和法预测了佛山市软土地面沉降量,并获得了研究区GMS三维立体沉降图,从中可以方便地查询任一点的地面沉降量,获得研究区地下的虚拟现实,具有形象和直观的特点;同时采用该方法还预测了佛山市软土地基经过地基处理和未经地基处理两种工况下地面沉降的未来发展趋势,结果表明研究区软土地基对建筑物的影响明显,修建建筑物时必须进行软土地基处理。
On the basis of standardizing all the drilling data in Foshan City, GMS software was used to construct the spatial framework of Quaternary soft soil in Foshan City. Based on the sand consolidation theory of Duzhaiji, the stratified summation method was used to predict the land subsidence And obtain the 3D sedimentation map of GMS in the study area, from which it is easy to query the ground subsidence at any point and obtain the underground virtual reality in the study area, which has the characteristics of image and intuition. At the same time, The future trend of land subsidence under the two conditions of foundation treatment and without foundation treatment shows that the influence of soft ground in the study area on buildings is obvious and the soft foundation treatment must be carried out when building the buildings.
