Experimental Study on Fire Resistant of Shield Tunnel Segment in Civil Engineering

Abstract:

Fire resistant behavior is one the main properties of shield tunnel segment in civil engineering. The main objective is to study the regularity of temperature distribution and deflection of shield tunnel segment after fire and the residual bearing capacity after cooling in this paper. According to the tests, a temperature-position fitting curve can be obtained, and it can be obtained that the damaged depth of segment is 7.8cm while heating in RABT curve for 125min. It is found that the residual bearing capacity of segment decrease with the increase of the pre-load, which drops rapidly for it is only about 20% compared to the reference one.
