摘要

Used as an alternative to disruptive open-trench methods, the doorframe slab method allows shallow tunnels to be built under city streets without extensive road closures. The doorframe technique derives its name from the mining industry, where inclined timber sidewall posts support a horizontal timber beam in excavated tunnels. The configuration of steel I beams or pipes driven into the ground supporting a concrete roof slab mimics that structure.
