摘要
着重介绍了中国博览会会展综合体室外展场的地基处理设计方案及实施情况。设计方案根据地基土原功能情况、应力历史情况,并结合展场的建筑功能划分特点综合考虑,选用清淤、清表、分层回填、限制正常使用阶段荷载分布形式、堆载预压结合排水固结等方法分区域进行了针对性设计,现场实施效果情况良好。另外,根据对现场实测数据的分析和拟合计算,推算出了场地堆载预压结束时的施工总沉降量、最终沉降量及固结度,计算结果与设计方案所依据的规范理论结果及沉降控制目标较为吻合,较好地验证了设计方案及设计参数选用的合理性。
The design alternative and implementation of foundation treatment project of outdoor venues of China Expro are introduced. The design alternative is based the primary function and stress history of foundation soils and the partition overall consideration of building function. Different subareas are pertinently designed. Treatment methods are desilting, clean surface, back-filling in layers, control of load distribution form for regular service, pre-compaction uniting consolidation and so on. The scene effect is fine. Moreover, the calculated final settlement, total settlement and degree of consolidation analyzed, and they agree with the actual measurement. The rationality of the design alternative and design parameters is thus validated.
