[摘要]以义乌万达广场项目C,D地块的地下室底板抗浮设计为例,对两种传统的抗浮锚杆布置方式进行了比较与分析,提出了改进的抗浮锚杆布置方式。并对采用改进的抗浮锚杆布置方式的抗浮锚杆与地下室底板进行分析,结果表明抗浮锚杆和地下室底板受力均比较均匀。最后对采用不同抗浮锚杆布置方式的基础造价进行比较,结果表明,采用改进的抗浮锚杆布置方式的基础单位面积的经济指标具有较明显优势。建议在地下室底板的抗浮设计中采用所提出的改进的抗浮锚杆布置方式。

Abstract:The anti-floating designs on bottom slab of basement of C and D blocks in Wanda Plaza in Yiwu were taken for examples to compare and analyze the rationality of two typical layout methods of anti-floating anchors, and improved layout method of anchors was proposed. Then anti-floating anchors and bottom slab of basement were analyzed with improved layout method. The results indicate that the stress of anti-floating anchors and bottom slab of basement are uniform. Construction costs of foundations with different layouts of anchors were compared, and the results indicate that the improved layout of anchor has obvious economic advantages in unit area cost. The improved layout method of anchor is recommended in the anti-floating design of bottom slab of basement.
Keywords:bottom slab of basement; anti-floating design; anchor; economy
