道路、桥梁结构(扶臂式现浇挡墙、桥台和闭合框架)中混凝土施工缝的形式,多为结构缝、装饰缝,近几年出现了温度缝。从缝的布设效果看,温度缝未达到彻底解决混凝土竖向裂缝的目的,其原因有多方面。本文通过近年来的工程实践总结的经验,论述了混凝土施工缝的布设问题,提出了以预留缝取代温度缝,解决混凝土竖向裂缝问题的观点,与同行进行交流和探讨。 Roads, bridges (arm-arm cast-in-site retaining wall, abutment and closed frame) in the form of concrete construction joints, mostly structural joints, decorative joints, temperature joints have emerged in recent years. From the stitching effect, the temperature does not reach the goal of completely solve the vertical cracks in concrete, for many reasons. Based on the experience of engineering practice in recent years, this paper discusses the layout of concrete construction joints, puts forward the point of reserving joints instead of temperature joints and solving the vertical cracks of concrete, and exchanges and discusses with peers.
