摘要
利用可视化编程语言Visual basic进行数据库系统的开发,根据开发出的数据库系统,将隧道瞬变电磁法数值模拟结果作为样本集存储到数据库中。在反演时,通过输入实测结果数据,将其与数据库中的数据进行比较,在数据比较中对同一模型下不同时间门所对应的数据赋予不同的权值,数据值大,则权值小,数据值小,相应权值就大,通过加权后的数据比较,得到与实测数据最接近的模拟结果,该结果所对应的模型,即为反演的结果。
Database system was developed by using Visual basic. Based on the database system, the results of simulating on TEM in tunnel were stored into database as sets of specimens by development of database system. The measured data were inputted and compared with the data in database while inversing. Data of the same model on different time were assigned matching weighting,value of data is large, weighing is small, value is small, weighing is large. The data in database closed to measured data were selected by compared the weighing data, the model corresponding to the selected data was the inversion result.
