摘　　要：对国外常规的半整体式桥梁进行了改进,并保留了传统式桥台构造中的某些优点,提出了新型的半整体式桥台设计,扩大了无缝桥梁的应用范围。通过多座无缝桥梁的设计、建造和多年的安全运营,证明本文中的改进型半整体式桥梁具有结构简单、受力明确和施工方便等优点,值得推广使用。The conventional integral bridges have some structural problems which limited its applications. In this paper, a new type semi-integral bridge is developed which combine the advantages of traditional joint-bridges and integral bridges. The successful operation of five semi-integral bridges in China proves that this new type semi integral bridges is easier to design and construct, and all have good operation, therefore the bridge is recommended to be constructed in large scale.
