摘　　要：高压输电线路跨越施工是一项风险极高的特种施工。施工过程中,主承托绳的受力、跨越架的稳定性,这两项核心参数事关整个跨越工作成败以及施工人员的生命安全。为了深入分析钢管跨越架及主承托绳在跨越工作中的受力情况,准确掌握跨越工作中风险最大点的情况,采用生物地理算法(BBO)对跨越架结构进行优化,通过ANSYS有限元对跨越架受力情况开展仿真分析,对跨越架主承力绳、拉线、钢管等受力情况开展讨论,对于跨越施工具有极强的指导意义。Crossing construction of high-voltage transmission lines is a high-risk special construction project.During the construction process,the stress on the main support rope and the stability of the crossing frame are two core parameters that affect the success or failure of entire crossing work and the safety of construction personnel.In order to deeply analyze the stress situation of steel pipe crossing frame and main support rope during crossing work,and to accurately monitor detailed situation of the highest risk point in crossing work,this paper applies biogeographical algorithm(BBO)to the structural optimization of the crossing frame.Through ANSYS finite element simulation analysis,it performs a detailed discussion on the stress situation of main support rope,stay wire,and steel pipes and other structures,which has strong guiding significance for crossing construction.
