摘　　要：通过对浅埋暗挖法、盾构法和顶管法等几种暗挖工法的比选,认为盾构法工艺先进,能够适应工程地质条件,不需要降水,可更好地控制地面沉降,是能够保证施工安全和工期要求的最优工法。Accord Pipe jacking meth ing to the comparison among Shallow buried-tunnelling, Shield driving and od, we think that the Shield driving method is the best. Because its technique is more advanced and it can meet above mentioned engineering and geological condition requirements. It can control surface subsidence effectively without dewatering. So it is the best method to ensure the safety of the construction and satisfy the time limit for the project.
