［摘要］以某淺埋地鐵停車線的單層雙跨結(jié)構(gòu)為例，運(yùn)用工程結(jié)構(gòu)優(yōu)化設(shè)計的基本原理，對結(jié)構(gòu)優(yōu)化前后兩個不同橫剖面結(jié)構(gòu)形式分別建立計算模型，然后進(jìn)行有限元計算，最后對結(jié)構(gòu)內(nèi)力計算結(jié)果和截面配筋分別進(jìn)行比較分析。結(jié)果表明優(yōu)化后的結(jié)構(gòu)受力體系簡單，不但能夠保證地鐵車站的安全穩(wěn)定，而且所用混凝土量和鋼筋量均小于優(yōu)化前的需用量，降低工程造價與施工費(fèi)用，可以為相似工程提供借鑒。

Abstract： The optimization design is applied in a single-layer frame structure of shallow-buried metro′s vehicle parking lines. Calculating models of two different cross sections of pre-optimized and optimized were separately set up, and then they were analyzed by the finite element method. Both the internal forces and the steel reinforcement about the frame structure were contrastively analyzed. The results indicate that the structure of optimization design is safe for use and the amount of structure materials can be cut down, which can provide guidelines for the similar engineering.
Keywords: vehicle parking lines of the shallow-buried metro; single-layer frame structure; optimization design; finite element
