Title: IMPACT OF SOIL LIQUEFACTION ON TRANSPORTATION FACILITIES
Accession Number: 00791608
Record Type: Component
Availability: Find a library where document is available Abstract: Liquefaction is often a concern in the planning and design of transportation systems in earthquake-prone regions, in particular with regard to earthquake loads. Yet decisions about relocation, mitigation, or design modifications to accommodate liquefaction are difficult because of the uncertainty involved in predicting liquefaction and its effects on transportation systems or facilities. The cost of such measures is often quite high, and owners are sometimes faced with the undesirable choice of doing nothing about potential liquefaction and accepting the risk of failure. This article describes the types of soil liquefaction failure, including flow failures, lateral spreads, ground oscillation, loss of bearing strength, settlement, and increased lateral pressure on retaining walls. It then discusses the impacts of soil liquefaction on transportation facilities, the difficulty of predicting the liquefaction behavior of a soil, and the designing of a facility so it can tolerate some liquefaction-induced movements.
