中文摘要:
      在试验的基础上,对均布荷载作用下钢筋混凝土圆、环形板式基础的极限承载力进行了研究.考虑环梁的约束作用,采用了不同于传统计算方法中的破坏机构,使板式基础的极限承载力得到较大的提高。通过试验分析,提出了三种破坏机构及相应的极限承载力计算公式,公式的计算值与实测值进行了比较,吻合良好.
英文摘要:
      In the light of the experimental observations, the ultimate capacity is ana- lysed for a circular or ring -shaped reinforced concrete slab foundation subjected to uniform loading. In consideration of the constraint being caused by the cur- led edge, the auther has adopted different failure mechanisms from those associ- ated with the conventional analysis, and thus increase the ultimate capacity fo the slab considerably. Three fallure mechanisms are suggested and the correspon -ding formulas derived. A good agreement has been found between the numerical resluts and the experiments, and hence the feasibility of the formulas.
