Innovative Foundation Alternative for High Speed Rail Application

One of the transportation solutions that have been always considered in the past few decades is the high speed rail (HSR) where plans for the HSR date back to the High Speed Ground Transportation Act of 1965 (Public Law 89-220, 79 Stat. 893). However, full implementation of an inter-state HSR has never been accomplished until recently the state of California started a HSR line construction that will connect the bay area to southern California. Bridges are key components of the HSR infrastructure and the state plan is to consider new construction as well as utilizing existing structure and foundation if appropriate. The inherent characteristics of HSR raise new problems beyond those found in typical highway construction, so comprehensive approach on the bridge structure and foundation system needs to be made to systematically tackle the challenges. Upgrading of existing bridges is of particular concern, e.g., (a) HSR bridge superstructures require high stiffness and are likely to be heavy, so upgrading of the existing structure for HSR will apply significant surcharge on the bridge foundation, for which a retrofit solution also needs to be developed; (b) The stiff, heavy components will induce seismic forces that are much higher than in highway bridges, so the accelerated bridge construction (ABC) solutions developed for highway bridges will have to be reworked to satisfy the more stringent requirements in seismic areas; (c) Construction issues also have to be optimized regarding how this upgrade can be best accommodated in a short period time without causing high costs and traffic disruptions
