Abstract: Several kinds of the cross section forms of reinforced concrete arch culvert for urban comprehensive utility tunnel using jacking construction method are discussed. Based on the advantages of square and circular concrete arch culvert, a combination type concrete circular arch culvert is designed. The concrete circular arch culvert are produced by using core mould vibration technology and local reinforcement measures and have the advantages of excellent durability, high productivity, easy installation, and the small jacking force.
