摘要
钢塔节段间常见的连接方式有“金属接触+高强度螺栓”连接与焊接连接两种,不管塔段间采用哪种连接方式,确保钢塔柱的成桥线形非常重要。以塔段间“金属接触+高强螺栓”联合受力钢塔柱为例,详细介绍了该类钢塔柱的建造难点及确保塔柱线形的技术措施,可供相关人员参考。
The common connection methods between the segments of steel pylon are two methods of"metal contact+high-strength bolt"connection and welding connection.It is very important to ensure the steel pylon alignment of the completed bridge in spite of the connection mode between the pylon segments.Taking the steel pylon by united stress of"metal contact+high-strength bolt"between pylon segments as an example,the difficulties to construct this kind of steel pylon and the technical measures to ensure the pylon alignment are introduced in detail,which can be referred for the similar projects.
