我国新修订的《工业建筑地面设计规范》(送审稿)中,对于量大面广的混凝土地面厚度的计算,采用了我国自己建立的计算公式。我国的计算理论的特点是在地面板的极限承载力的计算中考虑了推力。我们认为,这是反映了素混凝土地面板的实际工作机理的;因而,新的计算公式比原公式有着显著的进步。鉴于国内对于“推力”的问题尚存在着不同的看法,本文试图从通过试验观察到的一些现象出发,谈谈对此问题的粗浅认识,同时对新的计 In China’s newly revised “Code for the Design of Industrial Building Floors” (draft for approval), for the calculation of the thickness of concrete floors with a wide range, the calculation formula established by China has been adopted. The characteristic of China’s computational theory is that thrust is considered in the calculation of the ultimate bearing capacity of the ground panel. We believe that this reflects the actual working mechanism of the plain concrete floor slab; therefore, the new formula has made a significant improvement over the original formula. In view of the fact that there are still different views on the issue of “thrust” in China, this article attempts to discuss some of the phenomena observed through experimentation and talk about the superficial understanding of this issue, and at the same time,
