Taking the water-stopping construction of the post-pouring zone of an underground engineering as an example, this paper describes the construction technology requirements of post-pouring zone and reasons for improving the water-stopping quality of post-pouring zone. Through da- ta statistics, it analyzes factors influencing water-stopping construction quality of post-pouring zone, and puts forward corresponding preventive measures, so as to reach expected construction effect.%以某地下工程止水后浇带施工为例，阐述了后浇带施工工艺要求和提高后浇带止水施工质量的理由，通过数据统计分析了影响后浇带止水施工质量的因素，并提出了相应的预防措施，以达到预期的施工效果。
