浅谈大型地下车库设计中的裂缝控制

Discussion on crack control in the design of large underground garage

在地下大型车库的设计中,裂缝控制一直是困扰设计人员的一个难题。我国相关规范中明确了裂缝计算公式和裂缝控制要求,但是业界对地下结构的裂缝控制问题还有一定的争议。本文结合实际工程,从设计角度总结和分析地下车库设计中的裂缝控制方法和原则;提出针对不同的裂缝成因采用"放"与"抗",来控制裂缝的设计方法。

In the large underground garage design,cracking control is always a difficult problem for designers. In the specification of our country,the calculation formula of crack is defined and requirements for the cracking control is provided,but the cracking control problems have some controversies in the underground structure design. From the point of view of designer,the methods and principles for cracking control by the practical project were summarized; the design methods for cracking control by using the method of 'release ' and 'resistance ' for different causes of cracks was proposed.
