大体积混凝土的裂缝大部分是由于混凝土降温产生的温度应力引起的,采取有效措施防止温度应力造成混凝土表面和内部出现有害裂缝,一直是大体积混凝土结构施工中的技术难题。本文对大体积混凝土裂缝的成因进行了分析,探讨大体积混凝土的施工技术及要点,希望对建筑工程施工从业者在大体积混凝土的施工管理过程中能有所借鉴。
Most of the cracks in mass concrete are caused by the temperature stress caused by cooling concrete. It is always a technical problem in the construction of mass concrete structures that effective measures are taken to prevent the harmful cracks on the surface and interior of concrete caused by thermal stress. This article analyzes the causes of mass concrete cracks and discusses the construction techniques and key points of mass concrete. It is hoped that it can be used as a reference for construction workers in construction management of mass concrete.
