| 摘 要： | 有部分已建预应力混凝土空心板梁桥,运营没多久,就出现了裂缝,裂缝的出现给交通的安全运行带来了不安全因素,减少了桥梁的寿命。因此,如何在施工过程中有效控制潜在的裂缝,对于提高运营后桥梁的寿命有着至关重要的作用。本文以厦门疏港通道上一座桥梁为实例,详述了施工中防裂的一些重要措施。

| Abstract: | Part of the prestressed concrete plank bridges have appared cracks after not long to the traffic.Which have brought dangerous factors to the transportation, and reduced the bridge life. Therefore, how to control latent crack in construction process, which have the very important function of enhancing the bridge life.Take a bridge on the Xiamen sparse-port channel as an example, relate some important measures in the construction of guarding against the cracks |
