Bridge Construction

Bridges are a common feature of the built environment and one of the key elements of civil engineering. The basic principles of bridge design are dependent on the load-bearing structure; whether flat, convex or concave. The choice of bridge design will be determined by the height, ground conditions and the clear span required. Construction of the foundations is the first step toward building a bridge. This process involves detailed geotechnical investigations of the bridge site.

The type of bridge foundation has to be selected, such as the well foundation, pile foundation, and the opened foundation. Each foundation is suitable for specific soil strata, and the desired bridge characteristics. The soil characteristics will determine the load bearing capacity, and other important parameters. Depending upon the location and bridge type you have to adopt different methods for bridge construction.There are different methods of bridge construction, each of them is explained below.

The Principle Factors For the Selection Method of Bridge Construction

• Regularity of the span lengths
• Horizontal & vertical profiles of the bridge decks
• Soil strata
• Materials
• Site accessibility
• The time allowed for construction

Conclusion

Depending on the project requirement you have to adopt the method that suits your requirements. There are different types of methods and each comes with specific advantages. Choose the contractor that has experience.
