基于某供水工程大管径顶管施工引起地面沉降问题的思考

本次通过结合吉林引松供水工程中四平干线与高速公路交叉,利用peck提出的沉降计算理论,对于供水工程中大管径顶管引起的地面沉降计算,通过计算成果,为施工中精确控制提供依据,避免因地面沉降过大影响高速公路正常安全的运营。

Based on the settlement calculation theory put forward by Peck, this paper combines Siping trunk line and expressway crossing in Jilin Yinsong Water Supply Project to calculate the ground settlement caused by pipe jacking with large diameter in water supply project. Through the calculation results, it provides basis for precise control in construction, in order to avoid the impact of excessive ground settlement upon the normal and safe operation of expressway.
