摘要：
Analyzing the basic theory of stability, with a high pier of large span prestressed concrete continuous bridge as the example, the stability was analyzed when constructing, considering wind load, hanging basket, pier etc. Both eigenvalue and mode are got for the longest cantilever ting condition, the sensitivity of stability to various loads being analyzed. It is concluded that the unbalanced weight and the falling of basket are the main factors.
