Need help with my writing homework on Geo-Technical Design for Bridge Crossing a River. Write a 3500 word paper answering; The route connecting M2 with the A13 and M25 between junctions 29 and 30 will pass through sections such as Chafford Hundred, Grays, Tilbury, Gravesend, Instead rise, or Shorne Higham areas. These areas are prone to good development and thus enhance trade in the area.
The construction of other crossing sections is projected to decongest Dartford and thus create a long term solution to the current transport hurdle in the region. The success of every option taken in the design and geographical siting of the project is majorly comparable and contrasted in terms of merits and demerits of each model- highlighting distance shortness, lower financial incurrence, and decongestion level of the existent crossing.
Geographical redesign and expansion of the existing crossing would create a massive congestion delay and probably it would not result in desirable outcomes. The design of the route connecting M2 with the A13 and the M25 between junctions 29 and 30 in the river Thames demands extensive geotechnical research and preview. The outline of the geotechnical design entails an overview of the site geology, geotechnical cross-section with an indication of the expected soil profile. In-depth numerical analysis of a representative segment, highly detailed design of a representative section, appreciation, and regards for the uncertainty parameters entailed, recognition, and identification of the existing underground services that deals with the evaluation of the ecological issues and risk valuation and assessment. The entailed practicality of building the chosen option and lastly, the Sustainability of the projected design.
River Thames Anticipated soil profile which is the geotechnical cross-section of the project basing mainly consists of layers of river alluvium, river terrace gravels, tills, Cornbrash. Great Oolite limestone, upper and lower estuarine series, and upper Lias clay. The project is undertaken on the lower side of the river Thames which marks the deposition stage of the river.
