桥梁工程区气象安全保障系统的研究

根据国内大型桥梁建设工程区对气象安全保障的特殊要求及目前常规气象监测与预报预警的现状 ,笔者提出桥梁工程区气象环境监测、预报预警、安全保障建设的整体思路和技术框架 ,并据此研制成功一个基于通用分组无线业务 (GPRS) ,由工程区数据采集、分析及预报制作、信息传输、应急措施 4部分组成的桥梁工程区气象安全保障系统。该系统克服了以往桥梁施工气象安全保障中的缺陷 ,满足了建设部门随时随地掌握工程区当前和未来气象环境及其他安全保障对工程区气象基础数据的需求。系统应用于苏通长江公路大桥施工期的气象安全保障中 ,已取得明显实效 ,为该大桥建设规避气象灾害 ,降低不利天气条件影响 ,保障施工安全及施工计划安排提供了决策依据。

Study on Meteorological Safety Safeguarding System for Bridge Construction Area

Base on special demand on meteorological environment safety in the bridge construction area, as well as routine weather monitoring and forecasting status, a development scheme of meteorological environment monitoring, forecast, pre-alert and safeguard system for bridge construction area is put forward. A GPRS (General Packet Radio Service) based system composed of meteorological data collecting, analysis and forecast, information transmission and emergency response is worked out successfully. The system provides decision-making reference for bridgework and help to avoid meteorological disasters, ensure construction safety and lay down the construction plan. The system has been successfully applied to meteorological safeguard of Su-Tong Changjiang River Bridge and effectively reduces the influence of abnormal weather during the bridge construction period.
