摘要
对地下工程引起的地面沉降作实时准确的预报对指导施工有重要意义,利用动态灰色模型(MGM),可以根据适时更新的观测值建立实时的预报模型,从而使预报精度提高。文章通过工程实例,表明该模型能较好地应用于沉降预报,这对地下工程及岩土工程施工有一定的参考价值。
Real-time and veracious forecast of land subsidence is significant in subterranean engineer- ing. The dynamic grey model MGM can build real-time forecast model based on real-time observation data, consequently improves the precision of subsidence forecast. In this paper, based on an example in a subterranean engineering, the model is proved to be preferable in subsidence forecast and valuable for subterranean engineering and geotechnical engineering construction.
