摘要
地下洞室的合理设计基于三点要求：一是洞室形状应满足建筑限界要求；二是应满足结构受力要求；三是从经济观点出发，应使开挖断面积最小。本文提出的一种荷载一结构优化模型能自动地按这三点要求设计地下洞室，从而实现了地下洞室的自动优化设计。
A reasonable design of underground cave is performed on basis of threerequirements: the first is that the shape of the cave should be in the margin of construc-tion, the second is that the structure should be in a resonable loading state and the third is,froxn the economical point of view, that the excavated cross section should be minimum. Inthis paper, a load- structure optimization model was suggested by which the undergroundcave can be designed automatically to meet these three requirements and an auto - optimumdesign for underground cave can be realized.
