Abstract

In order to better understand the performance of the concrete pipe culvert reinforced by corrugated steel pipes，experiments were conducted on existing reinforced concrete pipes to determine the test-loading capacity of five specimens and understand the role of corrugated steel pipes． The influence of eccentric reinforcement on the loading capacity of the slip-lined pipe was explored and concluded with an approach to estimate the loading capacity of the reinforced pipes． The results show that the loading capacity of the concrete pipe culvert reinforced by corru- gated steel pipes mainly depends on the concrete pipes and the grout，and corrugated steel pipes plays a very small role． The loading capacity of an eccentric reinforced pipe was lower than that of a concentric reinforced pipe． The improved fully slip approach is reasonable，and the errors between the theoretical results calculated with the ap- proach for analyzing a vertical eccentric reinforced pipe proposed in this paper and experimental results is less than 22. 3% ．

Key words： pipe culvert reinforcement; slip-lining; concrete pipe culvert; mechanical mechanism; laboratory tests
