Based on the case study of Xiaolangdi Yellow river diversion project, the application of earth pressure balance pipe jacking technology was studied. After comprehensively evaluating project requirements and costs, DN 2 200 mm jacking prestressed concrete cylinder pipes (JPCCP) and a TYTP2800 earth pressure balance pipe-jacking machine were adopted. The proposed construction scheme effectively reduced ground disturbance caused by construction and enhanced control over ground settlement, thereby ensuring that construction quality and progress met the design requirements, which could serve as a reference for the application of pipe jacking technology in similar water conservancy projects.

基于小浪底引黄工程实例，深入研究了土压平衡式顶管施工技术的应用。通过综合考量工程需求与成本，选用了DN2 200 mm JPCCP混凝土管，并采用TYTP2800土压平衡顶管机进行施工。该技术方案有效降低了施工对地层的扰动，加强了对地面沉降的控制，从而保障了工程质量和进度符合设计规范，可为同类水利工程的顶管技术应用提供参考。
