随着灰砂砖在重庆市工业与民用建筑中被广泛使用,灰砂砖建筑物普遍发生裂缝的现象引起了人们的关注。自1982年开始,笔者带着这个问题并结合自己的工程实践对数十栋1至10层的灰砂砖建筑物(包括住宅、办公楼和库房等)进行了调查,对其中几栋建筑物裂缝的发生发展过程尚作了长期连续的观察。本文就是在调查的基础上,以裂缝 With the widespread use of sand-lime bricks in industrial and civil buildings in Chongqing, the widespread occurrence of cracks in lime-sand brick buildings has attracted attention. Since 1982, the author has carried out investigations on dozens of 1 to 10 floors of sand-lime brick buildings (including houses, office buildings, warehouses, etc.) with this issue and their own engineering practices. Several of these buildings have been investigated. The occurrence and development of cracks have also been observed for a long time. This article is based on the investigation, with cracks
