Abstract:A tremendous amount of scour data already exists for the highway bridges monitored by the Louisiana Department of Transportation and Development (DOTD). More than one hundred and twenty bridges are being monitored at a frequency of one to several times per year and at various locations from the bridges' centerlines.
The scour data collected is still in the format of traditional paper files and there existed a need to develop ready-to-use computer software using modern database technology to perform scour data management. Such software was needed to speed plotting historical cross sections and to identify scour critical bridges.
This report presents the manual of the software program developed for database management of scour data of the Louisiana highway bridges. The program has the capabilities of data retrieval of a specific bridge using a variety of data search routines. The program retrieves bridge information, survey plans, and soil boring data. It plots the cross-sections and longitudinal sections at any survey location and date. The program also displays contour plots at any selected date and historic plots of scour at any selected location.
The database software can be installed on any DOTD computer having Microsoft Windows 95, 98, and NT systems. The database can be installed in any directory in the user's computer or can be accessed remotely from the DOTD server.
