Abstract

As a new type of underground engineering reinforcement technology, the pipe-roof method has shown its significant superiority in shallow buried large section tunnel engineering in high traffic urban areas. According to the two design scheme of pipe-roof engineering, the 2-D numerical analysis model has been built to analyze the ground settlement. Results shows that the maximum value of surface settlement with 970mm pipes is about 20% less than that of 800mm pipes. The pipe with diameter of 800mm has several critical limits during the construction of pipe jacking. The pipe diameter of 970mm is the optimal recommended diameter for practical operation in pipe-roof engineering.
