Study on structural self-waterproofing of underground engineering

The author discusses how to reasonably determine the waterproof grade and how to select the reasonable structure form,the structure node design,main structure design and the steel bar arrangement from the aspect of the structure design,and puts forward the problems needing attention in the underground engineering,especially in the structural self-waterproofing design of the underground drainage structure and the civil defense,to make the waterproof design of the underground engineering more reasonable.
