A comprehensive review of incremental launching method in the construction of prestressed reinforced concrete bridges in Vietnam

Abstract

Abstract This paper discusses the implementation of the incremental launching method in the construction of prestressed reinforced concrete bridges in Vietnam. Since the 1990s, technology transfer has been initiated to develop and rapidly expand the country’s road and rail transport network system to support industrialization and modernization. Although the method was successfully applied in several bridge projects, the high construction cost has led to a controversial issue, and the government stopped its application in the country. The paper aims to analyze the limitations and unreasonableness in the project formulation, design survey, and procurement of technological equipment that led to the policy of stopping the application of the incremental launching method. The author provides an in-depth analysis to clarify the suitability of the policy and shed light on the issue’s root causes.
