宿淮铁路涵洞地基处理设计

根据换填砂夹石及水泥搅拌桩两种地基处理方法作用及使用范围,对宿淮铁路某涵洞进行前述两种方案比选,重点分析复合地基承载力及沉降等技术指标,决定采用水泥搅拌桩进行地基处理并阐述设计计算过程.根据复合地基试验报告认为,本设计结果有效.并按照宿淮铁路地质分布规律,明确本线涵洞地基处理主要采用上述两种办法,设计过程可参照上述涵洞工点.

The Design of Foundation Treatment for Su huai Railway Culvert

According to the role and use of range about two ground treatment methods of the replacement of sand with stone and cement mixing pile,making comparison and selection of the above two schemes for a culvert of the Suhuai Railway,this article focuses on the analysis of technical indexes such as composite foundation bearing capacity and settlement,decides to adopt cement mixing pile to doing foundation treatment and describes the design and calculation process.The design results is considered valid based on a composite foundation test report;and in accordance with the geological distribution law of the Suhuai Railway,we mainlyuse the above two approaches in the culvert foundation treatment of this line.The design process can refer to the above culvert.
