地下室墙壁开裂原因和预防研究--以银川基地某住宅楼工程为例

摘要

Nowadays, the premature wall-cracking of basement is a frequent quality issue in projects. In this paper, a residential building in Yinchuan Base was selected as a case to study on the reasons for wall-cracking of basement. And the results showed three factors resulted in wall-cracking, which contained excessive concrete heat of hydration, premature wall form removal and unhealthy maintenances. According to this, five precautions were propounded. Firstly, the structure function of horizontal rib should be attached great importance to. Secondly, post-poured strip should be set. Thirdly, hidden beam and pillar should be used. Fourthly, the heat of hydration should be reduced. Finally, the maintenances should be maximized.%地下室墙壁早期裂缝是目前工程中频频出现的质量问题。作者选取银川基地某住宅楼工程为例，对地下室墙壁开裂的原因进行了分析，认为导致墙壁开裂的因素包括混凝土水化热过高、墙体拆模过早以及养护不良。基于此，作者提出了重视水平筋的构造作用、增设后浇带、增设暗梁和暗柱、降低水化热、重视养护工作等五项预防墙壁开裂的措施。
