摘　　要：近年来,大体积混凝土因耐久性和承载性强等优势,在大体地下车站中的应用逐渐增加。然而,在施工过程中,受水泥水化热产生的温度效应及混凝土收缩性影响,大体积混凝土易产生裂缝。文章旨在探讨大体积混凝土的特点及裂缝成因,并提出相应的温度监测与裂缝控制措施,以提高大体积混凝土施工质量,为类似工程提供参考。In recent years,the application of mass concrete in large underground stations has gradually increased due to its advantages of durability and strong bearing capacity.However,in the construction process,mass concrete is prone to cracks due to the temperature effect generated by cement hydration heat and the influence of concrete shrinkage.This paper aims to explore the characteristics of mass concrete and the causes of cracks,and puts forward corresponding temperature monitoring and crack control measures to improve the construction quality of mass concrete and provide reference for similar engineering.
