Embodiment Construction
[0022] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.
[0023] Such as figure 1 As shown, a construction method of an integral abutment bridge with a dog-bone connection structure, including a bridge end girder 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 The weak shaft is subjected to bending, and the pile cap 2 and the end beam 3 are connected by a dog-bone connection structure. The 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 stiffness of the connection, increases the rotation capac...
