Problems solved by technology

A widely used bridge without expansion joints is the integral abutment bridge. Due to the cancellation of the expansion joints, the integral abutment bridge mostly uses H-shaped steel piles as supporting piles (large horizontal flexibility) to adapt to the longitudinal deformation of the bridge type. (generated by temperature changes, concrete shrinkage and creep, etc.), but it seldom considers the seismic capacity of the bridge type, and may also need to improve its seismic capacity
[0003] Concrete piles are usually used as the supporting piles of integral abutment bridges in my country (economical considerations), which have high horizontal thrust stiffness and poor tensile performance. The most important thing is that they cannot play a good role in energy consumption under earthquakes. Thus affecting the longitudinal deformation capacity of the bridge type, the service life especially the seismic capacity, and thus affecting the application of the bridge type in our country

Abstract

The invention relates to a seismic-resistant integral abutment bridge with energy absorption materials embedded in pier tops and a construction method of the seismic-resistant integral abutment bridge. The seismic-resistant integral abutment bridge comprises abutments, one sides of the abutments close to the earth are connected with connecting plates, the other ends of the connecting plates are connected with behind-abutment lapping plates, the connecting plates and the abutments are cast integrally, support piers are arranged below the abutments, miniature piers are arranged below the behind-abutment lapping plates and the connecting plates, the direction of the pier length or the long shaft of the support piers and the miniature piers is perpendicular to the longitudinal deformation direction of the bridge, and the energy absorption materials are filled between the tops of the support piers and the miniature piers and the surrounding earth, and the section of the energy absorption materials is identical with that of the piers. The seismic-resistant integral abutment bridge is simple in structure and reasonable in stress, the body damage of the support piers and the miniature piers is alleviated, and the seismic-resistant integral abutment bridge is high in longitudinal deformation and good in seismic resistance.

Description

technical field [0001] The invention relates to the field of bridges, in particular to an earthquake-resistant integral abutment bridge with pile tops buried with energy-absorbing materials and a construction method thereof. Background technique [0002] Bridges without expansion joints not only basically solve the problems of disease and maintenance and replacement caused by expansion joints and supports, but also improve the bridge's ability to withstand disasters and service quality. Over the past few decades, this type of bridge has been widely used in Europe and the United States. In recent years, my country has also begun to study and apply bridges without expansion joints. A widely used bridge without expansion joints is the integral abutment bridge. Due to the cancellation of the expansion joints, the integral abutment bridge mostly uses H-shaped steel piles as supporting piles (large horizontal flexibility) to adapt to the longitudinal deformation of the bridge type...
