［摘要］天津国家会展中心为会展类项目，对室外的承载能力要求很高。项目场地现状是水塘，需要回填，且下层土为深厚的软土，必须进行地基处理才能满足承载力和沉降的要求。这类项目的室外地基处理标准没有明确的规范依据，经过调研、专家论证、技术研究、经济性比较等方法，选择出适当的地基处理方案。最终方案综合考虑了工程地质特点、地基处理技术合理性、施工可行性、建设周期、工程造价等多方面因素，实现了安全可靠、经济合理的目标。［关键词］地基处理; 软土地基; 回填场地; 工后沉降; 沉降控制标准中图分类号：TU473 文献标识码：A 文章编号：1002-848X(2015)13-0057-05
Outdoor field foundation treatment design of Tianjin National Convention and Exhibition CenterWang Yang, Zhan Yongqin, Ma Ji(China Academy of Building Research, Beijing 100013, China )Abstract:Tianjin National Convention and Exhibition Center is an exhibition project which needs high bearing capacity of the outdoor field. The current situation of site is a pond that needs to be backfilled. The field subsoil is the deep soft soil. The foundation must be processed in order to meet the requirement of bearing capacity and settlement. The outdoor field foundation treatment standards of this kind project are not clear on the basis of specification. Through the method of research, expert consultation, technical research, economic comparison, the proper foundation treatment processing scheme was selected. The final solution, which considered the geological characteristics，rationality of foundation treatment processing technical, construction feasibility, period and the cost, can achieve the target of safe and reliable, economic and reasonable.Keywords:foundation treatment; soft soil foundation; backfill ground; post construction settlement; settlement control standard
