摘　　要：通过分析软土地层的管棚施工对地表沉降的影响因素,应用数值模拟计算,得出单、双层管棚施工导致的地表沉降值,分析单、双层管棚施工导致地表变形值的比值关系,并与实际工程监测值进行比较,得出一些有用结论和建议。To deal with the ground surface settlement that occurs when pipe roof method is applied in the soft ground,theoretical analysis and numerical simulation is employed.The values of ground surface settlement resulting in the construction of sole layer and double layer pipe roof are produced.By analyzing the ratio of settlement values caused by sole layer and double layer,and compared with the real values acquired by surveying and measuring on the construction field,some valuable conclusions and suggestions are presented.
