APPLICATION PROSPECT ANALYSIS OF HYBRID FIBER CONCRETE SUBWAY SHIELD SEGMENT
Main article
Abstract
With the rapid development of social economy, the urban population is increasing day by day, and the traffic pressure is increasing. Subway tunnels will be an inevitable trend to alleviate the pressure of urban rail transit. However, currently, the shield tunnel segments used in subway tunnel engineering mainly use ordinary reinforced concrete. The brittleness and low crack resistance of the material itself cause a large number of cracks and damage during the production, transportation, and construction of shield tunnel segments, directly affecting the safety and durability of subway tunnel engineering. In response to the many unfavorable factors of ordinary reinforced concrete subway shield tunnel segments, this article preliminarily explores the use of hybrid fiber concrete instead of ordinary reinforced concrete through various literature and on-site investigations. By utilizing hybrid fiber reinforced concrete which has a record of excellent performance, the various shortcomings of ordinary reinforced concrete subway shield tunnel segments can be compensated. The research results of this article provide an important basis for the development and production of hybrid fiber reinforced concrete subway shield tunnel segments.
