随着我国高等级公路建设的不断发展,预应力混凝土桥梁日益显示出广阔的应用前景。在此对预应力桥梁施工中常见的曲线孔道灌浆密实、金属波纹管孔道漏浆、预应力筋改变方向处混凝土开裂、曲线孔道竖向位置偏差等问题进行了简要分析并提出了治理方法。 With the continuous development of high-grade highway construction in our country, prestressed concrete bridges increasingly show a broad application prospect. In this paper, the common problems in the prestressed bridge construction, such as the dense grouting of curved hole, the leakage of metal bellows, the cracking of concrete in the direction of changing of prestressing tendons and the vertical position deviation of curvilinear channels are analyzed briefly and the treatment methods are put forward.
