| 摘 要： | 地下室底板往往都是大面积钢筋混凝土结构。由于岩石地基和基础的强大约束，当混凝土产生温度和收缩变形时，会有很大的拉应力，其拉应变甚至会大于混凝土的极限拉应变，从而导致底板开裂。本文从设计与施工两方面讨论了控制这种裂缝的有效措施。

| Abstract: | The base plate in a basement is usually made of a large area of reinforced conctetestructure. Because of huge restraint of ground and foundation,there is great tensile stressformed in the concrete when it is shrinking. The tensile strain is often even larger than theultimate tensile steam o'f concrete,resulting in cracks appearde in the base plate. This paperdiscusses the effective measures to control the cracking in the ase plate from the aspects ofdesign and construction |

| Keywords: | large area concrete shrinkage ground restraint non-shrink concrete. |
