摘要:
提出了按空间桁架理论设计桩筏基础的建议,并对18层框-筒结构进行了试设计和施工全过程的现场实测.实测结果表明,桩筏基础按空间桁架理论通过荷载等效简化并划分成有代表性局部模型的设计方法是可行的,据此,提出了扣除直接传递的荷载设计筏板以减少板厚和配筋等相应的设计建议.
Abstract:
Some suggestions about the pile raft foundation designed on the spatial truss theory are proposed, and the tentative design of an eighteen story frame-tube building and the field observation for the pile raft foundation in all the processes of construction are also presented. According to the result of the field observation, the design by load equivalent simplification and plotting out representative local models following spatial strut-and-tie theory are obviously practical, recommendations for design on the basis of the result are put forward, including skipping rafts processing straight transmittal function so as to induce thickness of the plank and use of reinforced steel.
