高速公路软基沉降预测系统及其应用研究

开发了软基沉降预测系统,把多种预测模型归纳起来建立模型库,应用数据库来管理和处理大量的现场观测数据,把模型库和数据库连接起来建立预测信息系统。结合数据库强大功能,提出并建立集工程概况数据库、变形监测信息数据库、沉降预测模型库和预测结果数据库为一体的软基沉降预测信息系统,且形成一个集查询、编辑管理、数据处理和沉降预测及其结果可视化等为一体的软件系统。最后,将该系统应用到广东省广梧高速公路软基施工监控中,提高了监控效率与预测效果。

A Study on Settlement Forecast System of Expressway Soft Foundation and Its Application

In this paper, many kinds of forecast models are summed up to establish the model base and a data base is used to manage and deal with a lot of observation data, then the model base and the data base are joined to build the forecast system. Last, the settlement forecast system is developed. On the basis of the powerful function of the database, this settlement forecast system is composed of geology information database, deformation monitoring information database, settlement forecast model database and forecast result database. Furthermore, this system establishes a system with the functions of inquiring, editing and management, data processing and settlement forecast, and visualization of the result. This system is applied on the construction monitor of Guan-Wu Expressway. The monitor efficiency is improved and the good predictive validity is achieved.
