摘　　要：针对围岩"上软下硬"复杂地质条件下,城市浅埋暗挖隧道下穿房屋段施工难度较大的情况,提出切实可行的结构设计方案,该方案从房屋地基加固、隧道支护结构、防排水、爆破开挖等方面提出具体的设计措施,以保证房屋、隧道结构安全。Because of the complex geological conditions of ＂upper-soft and lower-hard＂ surrounding rock, the construction of shallow-buried-ex- cavation tunnel underpassing of building in city is difficult. Aiming at it, this paper puts forward a feasible structural scheme design. According to the building＇s foundation reinforcement, tunnel supporting strueture, water proof and drainage and blasting and other aspects, it puts for- ward a concrete designing measure to ensure the safety of building and tunnel structure.
