摘　　要：支护和后背是桥涵顶进施工中重要的临时结构,对施工顺利与否、保证工期起着关键的作用。阐述了钢筋混凝土预制桩挡土墙和后背在达拉特电厂工程四期铁路专线下穿包东高速公路顶进桥施工中的应用,具体介绍了预制桩挡墙和后背的构造、计算方法及施工要点,可为以后类似工程的施工提供借鉴。The supporting and back structures are important temporary structures in jacking construction of bridges and culverts, and are of great importance in ensuring smooth construction and guaranteeing the time limit for a project. In this article, the author introduces the application of pre-cast reinforced concrete retaining wall and back to the jacking construction of the fourth--period special railway for the Dalate Electricity Plant, which underpasses the Baodong Highway. And the paper also shows the structure, calculation method, and key points in the construction of pre-cast reinforced concrete retaining walls and backs, thus providing certain experience for the construction of similar projects.
