信息化施工技术在地下工程中的应用

针对地下工程设计中“地质环境复杂，基础信息匮乏”的基本特点，结合具体隧洞工程，对信息化施工技术进行了分析探讨。设计和编制了工程数据库信息管理系统。利用现场施工监测取得的位移资料，用优化方法反演了围岩力学特性参数。利用反演分析求得的围岩力学参数，应用有限元法对该工程的施工过程围岩稳定性进行了分析计算。

Application of information technique to construction of underground engineering

According to the character of bad geology surroundings and scarce basic information in process of underground engineering designs, the technology of information design is discussed and analyzed combining a tunnel project. A project-database information management system is designed and developed. With the offset data obtained by in-situ construction method monitoring, the mechanical feature parameters of surrounding rock are obtained with optimal back-analysis method. The displacement of surrounding rock is calculated and the stability of surrounding rock is analyzed during tunnel construction progress by three-dimensional nonlinear finite element method with these obtained mechanical feature parameters.
