摘　　要：为了有效预防和处理影响市政道路桥梁工程的质量通病,研究过程着重分析了桥梁大体积混凝土结构温度裂缝的成因和桩基础常见的质量缺陷,进而提出有效的预防措施和处理方法。针对温度裂缝,设置内外部温度监测传感器,通过使用低热水泥、预埋冷却降温水管等措施控制内外部温差。对于桩基偏斜、桩体夹泥和桩体不完整等问题,提出综合运用钢护筒导向、泥浆护壁、钻孔过程测量与调控、成桩质量检测、桩体顶推法纠偏进行预防或处理。In order to effectively prevent and deal with the common quality problems affecting municipal road and bridge engineering,the research process focuses on analyzing the causes of temperature cracks of bridge mass concrete structure and the common quality defects of pile foundation,and then puts forward effective preventive measures and treatment methods.For temperature cracks,internal and external temperature monitoring sensors should be set up to control the internal and external temperature differences by using low-heat cement,embedded cooling water pipes and other measures.For pile foundation deflection,pile body mud,pile body incomplete and other problems can be prevented or dealt with by comprehensive use of steel drum guidance,mud wall protection,drilling process measurement and control,pile quality detection,pile body pushing correction.
