With the economic development of economy and t-he continuous expanding of building industry, the pipe jacking technology is applied more and more widely in the engineerin-g projects in the case of limits by construction conditions. It is usual y unavoidable to meet with barriers in the tunneling of p-ipe jacking. As a result of the application of pipe tacking in the certainn power plant in Nansha Section, the technological mea-sures for pipe tacking when meeting with barriers are summ-arized for reference.% 随着经济的发展，建筑业在不断发展。在施工条件限制下，顶管技术在工程中应用越来越多。而顶管在掘进过程中，遇障碍物常是不可避免的。现通过南沙区某电厂顶管技术的应用，总结顶管遇障碍物的处理技术，供借鉴。
