| 摘 要： | 大型地下室结构多为超长超宽混凝土结构，其平面尺寸大大超过规范允许的不设缝的最大限制长度。由于一般不允许设置伸缩缝，必须在总体和构造上采取有效措施来解决混凝土顶板由于温度收缩带来的抗裂问题。根据大型地下室结构的特点及多个大型地下室结构工程顶板裂缝分布情况可总结出顶板裂缝出现的主要原因，对裂缝可采取灌浆或覆盖一层新混凝土等处理措施。

| Abstract: | Most of big basement structures are super-long and super-wide, with plane sizes exceeding greatly the specification limit for arranging no construction joints. As no joints are allowed generally, overall and structural measures must be taken to prevent temperature cracks in the concrete top slab. Main top slab crack causes can be summarized up according to the characteristics of big basement structures and crack distributions in their top slabs, and crack can be treated by grouting or covering a new concrete coat. |
