摘要
浅谈泡桐坪隧道进出口堆积体及严重风化岩段在洞口浅埋、偏压条件下的隧道施工技术,重点对该段的地表加固、小导管施工、堆积体及强风化岩段的开挖与支护等技术作了详细阐述。
It is discussed the tunnel construction techniques for entrances and exits accumulated bodies and severe weathering rock section under the conditions of low-burying at the opening and bias voltage in Paotongping Tunnel. The focuses are given to the surface reinforcement, little tube construction, accumulated bodies and severe weathering rock section excavation and support.
