| Abstract: | With the Overpass across Panxi Road in Inner Ring Expressway of Chongcling as engineering background, this article studied the crack development situation of mass con- crete structures during construction process under the winter temperature drop conditions, used the finite element software to simulate the force status of bridge abutment structure under temperature drop loads,analyzed the effects of temperature drop on mass concrete structures,and proposed the treatment measures of mass concrete structures for the cracking of temperature drop,thereby providing the reference for the construction of mass concrete. |
