Embodiment Construction
[0026] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given in conjunction with the drawings, and detailed descriptions are made as follows.
[0027] Such as figure 1 As shown, a new integral abutment bridge with a dog-bone connection structure includes a bridge end beam 3, a pile cap 2 and an H-shaped steel pile 1 inserted into the ground surface as a supporting pile. The H-shaped steel pile 1 is weak The shaft is bent, and the pile cap 2 and the end beam 3 are connected by a dog-bone connection structure. H-shaped steel pile 1 can not only use its surface friction and even the end to bear the vertical load, but also make good use of its low lateral stiffness to allow horizontal temperature deformation. More importantly, the pile cap 2 and the end beam 3 The dog-bone connection structure reduces the rigidity of the connection, increases the rotation capacity of the connection, improve...
