摘　　要：杭州供电段管内沿海线路部分高铁站房内综合变电所地面沉降严重,既有电缆沟由于不均匀沉降导致破坏,现已不满足使用要求,变电所需进行地面整治,恢复其使用功能。整治过程临近营业线,综合对比结构抬高及地面注浆加固方式,在保证线路及既有站房结构安全前提下,采用重新浇筑结构地面的方案整治。The ground subsidence of the integrated substations in some high-speed railway station buildings at the coastal area in the Hangzhou power supply section is serious,and the existing cable trenches are damaged due to uneven subsidence,which no longer meets the requirements for use.Ground renovation in the substation is required to restore its use function.The renovation process is close to the business line.The structure elevation and ground grouting reinforcement methods are comprehensively compared.On the premise of ensuring the safety of the line and the existing station building structure,the plan of re-pouring the structure ground is adopted for renovation.
