Along with the daily progress of the society and everlasting development of economy, the application of pipe-jacking crossing technology is applied more and more extensively in oil and gas pipeline crossing engineering. However, the different pipe-jacking crossing modes should be selected according to different formation situations in practical application. This paper introduces the principle, characteristics and classification of atmospheric pressure balance pipe-jacking, and summarizes this construction technology in oil and gas pipeline crossing engineering in soft soil section with the engineering example of Zhongshan-Guangzhou natural gas pipeline.
