通过对泰州长江公路大桥钢塔柱预拼装方案的选择和关键工艺的研究，提出结构形式复杂的钢塔节段预拼装工艺选择原则。在研究了钢塔节段预拼环境的影响、支撑条件、金属接触率等水平预拼装关键工艺控制项点后，成功地解决了泰州桥钢塔节段水平预拼装中的技术难题。钢塔节段水平预拼装填补了我国钢塔制造的技术空白，为后续复杂钢塔节段水平预拼装方案选择提供了有力基础。

In this paper, we researched the key technology of the level pre-assembly of Taizhou Bridge steel tower, proposed the principle of the pre-assembly process in the complex structure steel tower. After studying the environment effect, supporting conditions and the metal contact rate measures, we solved the problem of the control points in process. Level pre-assembly of steel tower fills the technology gaps in China and provides a strong basis for the follow-up complex steel tower pre-assembled program.
