山区高墩大跨度连续刚构桥稳定性与参数影响分析
Stability of long -span continuous rigid -frame bridge with high piers in mountain areas in different construction stage and relevant parameter influence analysis
摘要
Abstract
On the background of a long -span continuous rigid -frame highway bridge with high piers in moun-tain areas,linear elastic stabilities were analyzed at the stages of completion of pier construction,the largest can-tilever and completion of the whole bridge for finding the minimum stability safety coefficient ,respectively.On this basis,nonlinear stability of the bridge was analyzed and the influences of nonlinear factors on stability were discussed.The influences of different parameters such as the concrete strength grade,longitudinal dimension of the pier,distance between the twin thin -walled piers,tie beam installation and foundation rigidity on stability were explored,and then some useful conclusions were drawn.The results can provide some references for the de-sign and construction of long -span continuous rigid -frame bridge with high piers.关键词
