摘要

从隧道施工引起地层变位的一般规律出发，分析了隧道施工对既有构造物的影响。结合长春站南北广场地下通道穿越既有轨道、站台、邮政通道及多处地下管线的具体情况，以规范规定的既有构造物允许不均匀沉降值作为控制目标，采用数学力学的基本分析方法，建立了相应的隧道施工地表沉降控制基准。所建立的控制基准，确保了工程安全、顺利地进行，并在工程中获得了实践验证。

Abstract

According to the general rule of ground deformation due to tunnel construction

the effect of tunnel excavation on existing objects is analyzed. Combined with the underground passage project between south and north square of Changchun Station

which crosses the existing rail lines

platforms

postal passages and several underground pipes

taking the permissible unequal settlement of existing structures in the code as controlling object

the controlling norm is established for surface settlement due to tunnel construction by basic mathematic and mechanical analysis methods. The established norm has assured the safety and smoothness of construction and has been proved by the construction practice.
