【摘要】 输电线路杆塔结构可靠指标及失效概率的分析研究,目前已经广泛应用于实际工程当中,本文着重研究了500kV同塔四回输电线路杆塔的可靠指标及失效概率。对于风荷载占控制因素的杆塔结构,本文研究了可靠指标计算参数组合对于杆塔失效概率的影响,同时计算了500kV同塔四回典型杆塔的可靠指标及失效概率,提出基于输电杆塔可靠度理论的杆塔风险规避的建议。更多还原

【Abstract】 The analysis and research of reliability index and failure probability of transmission line tower structure has been widely applied in practical engineering.This paper focused on the current reliability index and failure probability of 500kV four circuit in one transmission line tower.Wind load is the controlling factor of reliability index in transmission line tower structure.In this paper,the reliability index and failure probability of current 500kV four circuit in one transmission line tower were calculated,and the suggestion for risk aversion measures of tower based on reliability theory of transmission tower were proposed.更多还原
