摘　　要：大口径钢管顶管施工难度大,减小壁厚是途径,本文从工程实践和理论分析减小壁厚是可能的与必要的。希望这一对施工、投资都有利的措施能引起有关方面的重视。The larger diameter of steel pipe is harder for pipe jacking. For this, the best way is reducing the thickness of steel pipe. According to engineering practice and theoretic analysis, it is feasibe and necessary to reduce the thickness of steel pipe, which is benifi to construction and invest. And also the measure will be come to front.
