摘　　要：现代土木建筑工程,以混凝土结构占主导地位。混凝土施工过程中由于施工外界条件和自身强度在提升过程中发生变形、约束等因素的影响,会出现不同程度、不同形式的裂缝,是一个相当普遍和常见的现象,在大体积混凝土施工中表现尤为突出。本文主要介绍合肥市肥东县四顶山路下穿淮南铁路线立交工程封闭式路堑大体积混凝土施工路面裂缝产生的原因及整治处理措施。Modern civil engineering works are dominated by concrete structures.During the concrete construction process,due to the external conditions of the construction and the deformation and constraints of the strength during the lifting process,there will be different degrees and different forms of cracks.It is a quite universal and common phenomenon,and it is particularly prominent in the mass concrete construction.This paper mainly introduces the causes and treatment measures of cracks in the mass concrete construction pavement of the closed road cutting of the Huainan Railway Line Interchange Project under the Sidingshan Road of Feidong County,Hefei City.
