大面积地面防裂施工技术与措施

地面工程的空鼓、裂缝及起砂是常见的质量通病，针对上述情况，结合两项较大地面工程施工，在传统工艺的基础上，采用了改变工艺作法，设置分格条、增加伸缩缝等措施，同时要注意施工季节来控制伸缩缝的长短，面层分格与下层结构对齐以控制施工质量。工程自投入使用以来，未发现变形痕迹，因此说，改进工艺可行，措施切实。

Construction technique and measures of large area land surface against cracking

Empty, cracking and sugaring of land surface constr uction are quality common failings. In view of the above situation, combining with construction of two more land surface projects, on the basis of traditional technology, the pape r adopts measures of changing technology practice, installing cellular and addin g expansion joint, pays attention to construction season to control length of ex pansion joint at the same time, aligns understructure and surface course cellula r to control construction quality. Since land surface of two examples is put int o use, deformation marks have been not found, so improving technology is practic able, measures are practical.
