T-shaped rigid frame bridge broken pier jacking construction method based on zero stress increment
The invention discloses a T-shaped rigid frame bridge broken pier jacking construction method based on zero stress increment, which comprises the following steps: selecting a bridge pier cross section along a to-be-cut bridge pier, and symmetrically arranging a first side-span pier jack and a second side-span pier jack on two sides of a support respectively; arranging a first-span near-bridge-pier jack and a second-span near-bridge-pier jack symmetrically; and after a first-span main beam control section of the first-span main beam and a second-span main beam control section of the second-span main beam are symmetrically arranged on the edge of the bridge pier, cutting the bridge pier, jacking, lapping and pouring. According to the method, T-shaped rigid frame bridge broken pier jacking based on zero stress increment can be achieved, the structure is simple, operation is safe, and engineering implementation is facilitated.
本发明公开了一种基于零应力增量的T型刚构桥断墩顶升施工方法，其中：选择沿要截断的桥墩的桥墩截断面，以对称方式分别于支座两侧设置第一跨边墩处千斤顶和第二跨边墩处千斤顶；以对称方式分别设置第一跨近桥墩处千斤顶和第二跨近桥墩处千斤顶；以对称方式于距离桥墩边缘设置第一跨主梁的第一跨主梁控制截面和第二跨主梁的第二跨主梁控制截面后进行桥墩的截断、顶升、搭接和浇筑操作。本发明提供方法可实现基于零应力增量的T型刚构桥断墩顶升，结构简单，操作安全，便于工程实施。
