摘　　要：介绍长距离顶管施工的特点和郑东新区的地质条件。通过本区长距离顶管工程实例指出传统理论计算顶进阻力结果与实际存在的差异。根据顶力监测结果反算摩阻力,准确计算总顶进阻力,提高了施工效率,创造良好的效益。This paper introduces the geological conditions of Zhengdong new district and characteristics of long distance pipe jacking construction. Through the long distance pipe jacking engi- neering examples the differences between calculation results and actual jacking resistance existed in the traditional theory is indicat- ed. According to the monitoring results the frictional resistance is back-caleulatedand total jacking resistance is accurately calculat- ed, which improve the efficiency of the construction and create a good benefit.
