Billet optimization can greatly improve the forming quality of the transitional region in the isothermal local loading forming (ILLF) of large-scale Ti-alloy rib-web components. However, the final quality of the transitional region may be deteriorated by uncontrollable factors, such as the manufacturing tolerance of the preforming billet, fluctuation of the stroke length, and friction factor. Thus, a dual-response surface method (RSM)-based robust optimization of the billet was proposed to address the uncontrollable factors in transitional region of the ILLF. Given that the die underfilling and folding defect are two key factors that influence the forming quality of the transitional region, minimizing the mean and standard deviation of the die underfilling rate and avoiding folding defect were defined as the objective function and constraint condition in robust optimization. Then, the cross array design was constructed, a dual-RSM model was established for the mean and standard deviation of the die underfilling rate by considering the size parameters of the billet and uncontrollable factors. Subsequently, an optimum solution was derived to achieve the robust optimization of the billet. A case study on robust optimization was conducted. Good results were attained for improving the die filling and avoiding folding defect, suggesting that the robust optimization of the billet in the transitional region of the ILLF was efficient and reliable.

桥梁和房屋建筑受力特点不同,因此铁路、公路以及工民建行业在桩基承载力计算上有着不同的认识和理解,特别是在桩端阻力的处理上很不一样。三岔双向挤扩灌注桩是近年来兴起的一种多点支承的新型变截面桩,其盘阻力占到了总承载力较大的比例,往往超过30 %。在设计该桩型时,采用不同行业规范将出现较大的差异。通过研究不同规范中的计算方法,并依据已有详细准确资料的18个工程,对DX桩在铁路工程中的设计方法进行了研究。

通过数值计算对不同桩间距的DX桩群桩进行了分析研究。结果表明:DX桩的群桩效应随着桩间距的减小而逐渐明显,间距为6倍桩径的群桩极限承载力是间距为3倍桩径的群桩极限承载力的1.32倍;群桩间距由3倍桩径增大为6倍桩径时,群桩效应系数由0.59增大为0.78;群桩间土体沉降的最大值发生在两扩盘中间位置处,且随着桩间距的增大而减小。
