针对珠三角城际铁路首次下穿运营机场的问题，通过广泛的资料调研和实地考察，结合工程实际，提出了穗莞深城际铁路下穿深圳机场道面沉降控制标准。结合飞行区环境条件及特殊的沉降控制标准，采用三维数值分析方法对盾构隧道施工过程进行模拟分析，给出了施工过程对土体扰动的程度及影响范围，计算了不同埋深的地表沉降。根据分析结果提出了穿越过程修正的沉降控制标准。根据飞行区地表复杂的环境提出了施工过程的道面监测建议，即在非道面区架设自动全站仪，对指定道面进行全周期无棱镜自动扫面，以解决飞行区人员准入难、不准埋设监测点等问题。

Aiming at the problem of Pearl River Delta Intercity Railway under passing the airport for the first time,based on a wide range of investigation and fieldwork,combined with the actual situation of the project,a settlement control standard of Guangzhou-Dongguan-Shenzhen intercity railway undercrossing Shenzhen Airport pavement is put forward in the paper. Combined with the environmental conditions and the special settlement control standard of the flight area,3D numerical analysis method is applied to simulate the construction process of shield tunnel,the degree and influence area of the construction process to soil disturbance are obtained and surface subsidence of different buried depths is calculat-ed. According to the analysis result,the revised settlement control standard is proposed. Suggestions on pavement moni-toring during construction process are put forward according to the complex environment in the flight area. The automatic total station is erected in non-pavement area to perform whole cycle prismatic-free automatic scanning on the specified pavement to solve the problems such as difficult admittance of personnel in flight area and no monitoring point embed-ded.
