| TBS無砟軌道上部結(jié)構(gòu)層優(yōu)化設(shè)計(jì)與參數(shù)分析(17 卷) |
| 英文標(biāo)題 |
| Parameters analysis and optimum design of TBS抲pper structure layer |
| 摘要 |
| 運(yùn)用多重疊合梁模型對TBS無砟軌道上部結(jié)構(gòu)層進(jìn)行優(yōu)化設(shè)計(jì)和參數(shù)分析，并編制相應(yīng)的MATLAB計(jì)算程序。計(jì)算結(jié)果表明：增大道床板寬度、支承層厚度以及防凍層彈性模量將有利于降低上部結(jié)構(gòu)層拉應(yīng)力水平，而增大道床板厚度和彈性模量則不利于結(jié)構(gòu)受力。 |
