根据我国桥涵规范,当桥梁墩台基础αh≤2.5时,可视为刚性基础工作,其中α为基础的变形系数,h为基础的埋置深度。这一刚性受力条件的假定使基底的弯矩及转角增大,与按温克尔介质上的弹性基础理论所算得的结果相差甚大,须加以修正。本文对支立于土上和嵌入岩层内的基础,结合现行规范提出修正系数表。 According to the specifications of China’s bridges and culverts, when the bridge pier foundation αh ≤ 2.5, it can be considered as a rigid foundation work, in which α is the basis of the deformation coefficient, and h is the foundation of the buried depth. The assumption of this rigid stress condition increases the base’s bending moment and angle of rotation, which is very different from the result calculated by the elastic foundation theory on Winkel’s medium and needs to be corrected. This paper proposes a correction factor table based on the current specifications for the foundations supported on soil and embedded rock formations.
