采用多弧离子镀技术制备了不同调制比的交替多元多层Zr/CrAlSiN复合涂层,通过交替沉积与间歇性接近不同靶材相结合的方法获得了Zr/[Al(Si)N/CrN]“层中层”结构,并对复合涂层的力学性能、无腐蚀时的摩擦磨损性能、无摩擦磨损时的腐蚀性能及海水环境中的腐蚀磨损性能进行了研究.结果 表明:该结构设计对涂层生长缺陷具有明显的抑制和修复作用;随着CrAlSiN层厚度比例增大,调制比为1∶6时Zr/[Al(Si)N/CrN]涂层的综合力学性能最佳;由于CrAlSiN层具有多层Al(Si)N/CrN结构,增加CrAlSiN层厚度比例增加了复合涂层横向界面,从而提升了涂层腐蚀性环境中的阻隔作用,因此CrAlSiN层厚度比例的增加既可以提升无摩擦磨损时涂层的耐腐蚀性能,又可提升涂层摩擦开动后的耐腐蚀性能,并进一步降低涂层腐蚀和磨损的相互促进作用;当调制比为1∶6和1∶8时,Zr/[Al(Si)N/CrN]涂层在海水环境中展现出了较好的抗腐蚀磨损性能.

通过大型振动台模型试验研究了减震层效能评定方法的准确性和减震层作用下衬砌结构与最不利的IV级和V级围岩在激振过程中的相互作用.研究结果表明:减震层效能评定方法可以较为准确地评估减震层在地震动力作用下对衬砌结构的作用效果,但随着激振加速度峰值的提高,试验值会与评估值产生偏差,因此对减震层效能评定方法引入地震动力损伤系数以提高其精确度;围岩级别相较于减震层的厚度对衬砌结构的地震响应更具有决定性作用;在中低烈度地震区,减震层对衬砌结构的保护效果较为明显,但减震层存在最优厚度,超过该厚度,衬砌结构遭遇地震时的震动

微分求积法和单步块方法都是单步多级数值方法,但是直接应用于求解非线性动力方程时的计算量比较巨大,为此提出了一种基于单步块方法的改进精细积分单步方法.结合精细积分法,该方法采用s级的单步块方法的第s个方程对Duhamel积分项进行数值积分.具体采用四阶Runge-Kutta法获得待求变量的预估值,并采用新四点积分公式计算Duhamel积分项.相对于现有的单步方法,该改进算法在数值精度和稳定性上更优.通过非线性动力方程的典型算例验证了该算法的优势.
