Yes, and no. It will depend on the soil type. Many such places are built in the middle east, Australia, Vietnam, France, etc. Personally, I'd only attempt it with fully reinforced walls. I'd get out and shape a small section as a full arch, spray the walls with truckbed liner then with reinforced shotcrete then again with truckbed liner. Then dig the next section.
