| Highway bridges in the operating process, bear the load and the environment against. It will inevitably cause changes in the structure function, and the state of deterioration affect bridge traffic safety. As different bridge differences in the degree of deterioration larger impact on the level of bridge deterioration and there are still many influence, in the grasp of the state highway bridge practical work, we must build a Diseases database and Evaluation System. At the same time various indicators of evaluation were given different weights, so the operators make the right monitoring and evaluation.In light of the above reasons, the paper belongs to the part of Western Traffic transportation construction projects, "long-span bridge monitoring, reinforcement, conservation technology package". The following aspects were studied: Through books, the network to collect various diseases ,Arch Bridges are divided into the steel arch bridge, reinforced concrete arch bridge and pipe concrete arch bridge three categories and diseases were attributed to the location, which makes all kinds of diseases can be a convenient access to more clearly understand,and each summed up well the causes of disease and disposal recommendations.Finding out the management database system of the Highway bridges at home and abroad to identify disadvantages benefits and, in conjunction with this project, summed up the characteristics developed in this paper the characteristics, in addition to data storage and preliminary analysis of the disease, did not join the past Implementation of the network, and remote real-time modify, add and delete function.Combination of the above points, development Arch disease database using SQL Server 2000, ASP.Net and Microsoft Visual Studio 2005, and other techniques and tools, as well as integration of Web applications, the popular integrated development tools DreamWeaver MX 2004, the overall design of software engineering methods followed through needs analysis, design, text stalls and the establishment code, module and system testing several stages of development. Achieve the following key features: Developed a simple, easy to use, applicable to all levels of management unit of the highway pavement management database; Bridge Information fast and accurate data query , to the effect illustrated; Data maintenance, according to the actual time of the data findings add, edit, delete, print, data adjustment, the system can easily update; Summing up the previous bridge diseases on the basis of analysis and evaluation, in view of the disease appeared in the bridge position and phenomena through systems analysis and research to determine a scientific and rational Arch diseases and causes of the proposed disposal and evaluation index system and the system stay in a convenient and efficient realization can modify, add and delete this system module; All operations and functions are realized through the network, truly a distant land near. |
