偏压连拱隧道结构优化设计应用研究

Applied research on structure optimization design for shallow double-arch tunnels

介绍了应用遗传算法对偏压连拱隧道断面形状及衬砌进行的结构优化分析,得到了最优的隧道断面形状及衬砌参数,改善了连拱隧道受力,既保证了结构的安全度又降低工程造价,经工程实例应用得到了验证,具有较好的经济效益和推广应用价值。

The paper introduces the applied inheritance calculation to have the structural optimal analysis of the sectional shapes and lining of the shallow double-arch tunnel,concludes the optimized tunnel section shapes and lining parameters,so as to improve the stress of the double-arch tunnel,ensure the structural safety and lower the engineering costs,and concludes the checking by applying in engineering examples,so it has better economic benefits and application value.
