Based on coordinating relations of steel and concrete, the grillage structure finite-element method was adopted to analyze the space mechanical effect of curved girder bridges. 本文針對曲線(xiàn)梁橋空間力學(xué)分析的復雜性，提出了采用基于鋼混協(xié)作關(guān)系的格柵結構有限元法來(lái)分析曲線(xiàn)梁橋的空間力學(xué)效應。
The geometrically combined relation of the syncline stucture with the pit controls the mechanical effect of the stuctural plane and rock mass structure. 向斜構造與采場(chǎng)的幾何組合關(guān)系控制著(zhù)結構面和巖體結構的力學(xué)效應。
