基于Visual Basic及Access的工程资料档案管理系统开发

在社会日趋发展和信息技术取得巨大进步的今天，许多勘查设计单位原有的工程资料管理方法已不能完全满足社会各方面工程实践的要求，使用先进的工程资料管理系统是必不可少的。因此，工程资料档案管理系统是一卜具有重要理论研究意义及广阔应用前景的研究课题。文章结合鹧鸪山隧道这一重大工程，利用visual Basic和Access开发了一个适用于广大工程建设资料管理的软件。在系统开发过程中，解决了以下问题，即利用WinRAR软件实现文，牛的压缩及解压缩，利用SQL语言实现文件多种查询方法。通过调用文件存放地址实现文件的打开功能。工程资料卡当案管理系统的使用将解决工程实际中存放、保管资料的各种问题，消除了传统资料保存方式的弊端。工程资料档案管理系统具有使用方便、查询快捷等优点，具有实用价值和推广价值。

Monitoring and warning of Gushuixi Landslide in Fuling District, Chongqing

Chongqing region belonging to the red beds area, distributes many bedded slopes or weak foundation slopes constituted with the red or gray mudstone and mottled sandstone, which is one of the most serious landslide hazard regions in the country. This paper discusses on the application of the method of crack observation in landslide monitoring, Gushuixi Iandslide in Fuling District, Chongqing at the example. The crack marks are established, and the data is collected according to the monitoring period. Based on the analysis of the crack monitoring data and a period of effective monitoring, an early warning was done successfully. More than 100 people withdrawn safely and the loss of properties was decreased for more than 15 millions yuan. The good result is received because of the application of crack observation method in landslide monitoring. The crack observation method is an effective and basle method for geological disaster monitoring and warning for public prevention.
