［摘要］《建筑地基基礎設計規(guī)范》（GB 50007—2011）第8411條規(guī)定：梁板式筏基底板厚度應滿足受沖切承載力、受剪切承載力的要求?；谠撘?guī)范第8412條，通過詳細的推導和計算得出：對于梁板式筏基，其底板厚度在滿足基本構造要求下由受剪切承載力控制，受沖切承載力不起控制作用。工程實例也證明了此結論。因此，結構設計時可只根據(jù)受剪切承載力計算確定梁板式筏基底板厚度。

Abstract:On the provision 8411 of  Code for design of building foundation (GB 50007—2011), the thickness of base plate for waffleslab raft should be derived by punching calculation and shearing calculation. Based on the provision 8412 of the code, it was obtained by detailed deduction and calculation that the thickness of base plate for waffleslab raft is determined by shearing calculation and is not determined by punching calculation. The same conclusion can be proved by engineering cases. So the shearing calculation is only needed for the thickness of base plate of waffleslab raft.

Keywords: waffleslab raft; punching calculation; shearing calculation
