研究结论:（1)利用Peck理论公式计算的地表沉陷槽与长江隧道盾构施工引起地表沉陷槽实际情况基 本相符,Peck公式在武汉地区具有较好的适用性;（2)建筑物受影响程度主要取决于隧道埋深和建筑物距隧 道距离、盾构施工引起的地层损失率等情况,隧道埋深和建筑物距隧道的距离越小、地层损失率越大,则地面 变形和建筑物变形也越大;（3)隧道施工引起建筑物的破坏等级可分为5类，对于受影响程度为I~II级的 轻度影响建筑物，可以不采取保护和处理措施;对于受影响程度为III ~ V级的建筑物，必须事先采取有效保护 措施。

Research conclusions；(1) The surface subsidence calculated by Peck Formula is consistent with the actual situation, so Peck Formula has better applicability in Wuhan. (2) Damage level of the building caused by tunnel construction mainly depends on the buried depth of the tunnel, the distance of building to the tunnel and strata loss caused by the construction. The less buried depth of the tunnel and the less distance of building to the tunnel cause larger loss of strata, resulting in larger deformations of surface and building. (3) Damage levels of the buildings caused by tunnel construction can be divided into five categories. To the I and E extent affected buildings, it does not need to take the measures for protection and treatment. To the extent IH - V extent buildings, it must take effective measures for protection.
