摘要
以上海地铁18号线某出入口冻结工程为例,采用数值模拟方法,对富水粉质黏土地层中出入口冻结温度场发展规律进行了研究。研究表明,冻结期间,出入口冻结温度场发展规律分为快速降温、潜热释放、稳定降温、趋于平缓四个阶段。研究结果为类似工程施工设计提供参考。
Taking an entrance and exit freezing project of Shanghai metro line 18 as an example,the development law of entrance and exit freezing temperature field in water rich silty clay layer is studied by numerical simulation method.The research shows that the development law of inlet and outlet freezing temperature field during freezing can be divided into four stages:rapid cooling,latent heat release,stable cooling and flattening.The research results provide a reference for the construction design of similar projects.
