摘要
高速铁路技术标准要求高,如何合理选择斜底深厚流塑状软土地基加固措施是设计的关键。结合西南地区高速铁路某车站中斜底软弱地基处理实例,采用桩筏结构、桩网结构,配套反压护道、桩顶系梁等综合措施,解决斜底软土地基加固问题。
High-speed railway requires high technical standards,and how to reasonably choose foundation reinforcement measures for deep fluid plastic soft soil foundation with inclined bottom is the key to design.Combined with the treatment example of soft foundation with inclined bottom at a high-speed railway station in southwest China,the pile-raft structure and pile-net structure are adopted,and the comprehensive measures such as back pressure berm and tie beam at the top of pile are matched to solve the reinforcement problem of soft foundation with inclined bottom.
