摘　　要：依托哈大客运专线鞍山西站CFG桩板复合地基加固工程,采用有限元程序对桩板复合地基的应力、沉降等承载特性进行了分析,并结合实际沉降观测结果,推算出了地基最终沉降及工后沉降。计算和实测结果表明,加固后的地基沉降远小于天然地基沉降,沉降控制效果明显,工后沉降满足高速铁路无砟轨道要求。Relying on CFG pile-slab composite foundation reinforcement engineering for West Anshan Station of Harbin-Dalian Passenger Dedicated Line,the bearing characteristics of pile-slab composite foundation such as stress and settlement are analyzed using finite element program.Combined with actual settlement observations,the final settlement and post-construction settlement are calculated.It is shown from calculation and measurement that settlement is much less in reinforced foundation compared to unreinforced foundation.The control effect is significant and post-construction settlement satisfies the requirement of high-speed railway ballastless track.
