南京机务段工程,位于一片厚薄不均的杂填土地基上,填土最大厚度达4m,局部地点还夹有大量煤屑。场地北面,有一条横贯东西3m深的水沟,地质及地貌情况均比较复杂。由于生产工艺的布局和用地限制,一些生产房屋必须建在一定的位置上,难以避开复杂的地基。为此,如何处理好这种复杂的地基,使得建筑物既安全可靠,施工简便易行,又减少建造费用,成为一个研究 Nanjing locomotive depot project, located in an uneven thickness of the miscellaneous fill foundation, fill the maximum thickness of 4m, some sites also hold a lot of coal. To the north of the site, there is a ditch crossing 3m deep and east-west. The geological and geomorphological conditions are rather complicated. Due to the layout of the production process and land use restrictions, some production houses must be built in a certain position, making it difficult to avoid complex foundations. To this end, how to deal with this complex foundation, making the building safe and reliable, easy construction, and reduce construction costs, a study
