Crack Controlling Research of Concrete Foundation for Large Equipment in Winter Daxing Qian Civil Engineering Department, Luoyang Institute of Science and Technology，Luoyang，China，471023 qdx941@sohu.com Keywords: Concrete Foundation; Large Equipment; Crack Controlling Abstract.
Cause Analysis of Cracking Formation Comparing with the foundation of architecture engineering, the raft of length and width is the relatively large, the smaller the thickness, princiole evaporating more equipment Foundation is fast and this underlying internal heat dissipation Slower, internal heating faster; Additionally, because of the reasons for a lower temperature, the faster the external heat dissipation, results in a large internal and external temperature difference.
