用新的气压加载法求空腹重力坝优化断面模型的超载能力

本文利用新的气压加载法对经过优化设计的空腹重力坝断面模型与原设计的断面模型进行破坏试验对比，其结果为：前者较后者在体积节约９．１％的情况下，仍能保持同样的超载能力，从而，用实验验证了优化断面的优越性．

THE CALCULATION OF OVERLOAD ABILITY OF OPTIMUM SECTION MODEL FOR HOLLOW ABDOMEN GRAVITY DAM WITH NEW PNEUMATIC LOADING METHOD

A new loading method with a triangular pneumatic bag is used for doing experiments up to failure in order to compare the overload abilities between the two separate cases of the optimum hollow abdomen gravity section model and of the original design. The result is that the former, in spite of its 9. 1% saving in volume ,keeps the same overload ability equally well as the latter. The superiority of the optimum section is thus proved by our experiments, and the new loading method is introduced in detail.
