对趾板分缝问题的探讨

Discuss on partitioning the plinth by slits

在我国关于趾板分缝存在不同意见。趾板不分缝，若不采取一定措施，其裂缝对工程可能是有害的；趾板分缝，可以有效地减小裂缝的危害，但止水设计复杂且易留隐患。已有工程实践表明，趾板不分缝，采取预留宽槽跳仓浇注可能是解决趾板裂缝的有效途径。

There are different opinions on the portioning the plinth by slits in our country. If there is no slit on the plinth and no countermeasures, then crack could be harmful to the project. And if there are some slits on the plinth, then the cracks will be less harmful to the toe plate, but the design of permeter joint is complex and cause some hidden trouble. It is shown by engineering practice that if the plinth is not partitioned by slits the problem may be solved by wide trough left in advance.
