Answer:

They are maintained by coating the inside of the tunnel with some kind of leak-proof lining to protect the surface of the dirt. This is maintained the way any building cladding of that material is maintained.

The physics of being perfectly round distributes forces naturally. Why don't underground tunnels collapse on themselves?

“Look at the shape of the tunnel, they are circular to spread the load, the same idea as deep sea diving vessels have spherical living areas. There are no sharp corners. …

“Look at it slightly differently, how does a soap bubble keep it's shape, against the atmospheric pressure. It spreads the load to avoid pressure build up in one place.”
