摘　　要：由于整体性好、机械化程度高、水下施工简便等优势,模袋混凝土被越来越多的用于水利工程护坡。然而,模袋混凝土护坡在冬季结冰期受坡向冰推力和垂向冰压力双重作用,极易发生破碎、断裂,从而失去防护功能。文章将纵向加强筋植入模袋混凝土,以此达到延长模袋混凝土使用寿命以及增强其受剪抗弯性能的目的,并以实际工程验证了植筋式模袋混凝土的可行性与适用性。Due to the advantages of good integrity,high degree of mechanization and simple underwater construction,molded bag concrete is more and more used for slope protection in water conservancy projects.However,due to the double action of slope ice thrust and vertical ice pressure,the molded bag concrete revetment can easily break and lose its protective function in winter freezing period.In this study,longitudinal reinforcement was implanted into the molded bag concrete,so as to extend the service life of the molded bag concrete and enhance its shear and bending resistance,and the feasibility and applicability of the reinforced molded bag concrete was verified by practical engineering.
