摘要
该文从工程实践出发,对用于计算双圆盾构法隧道地表沉降的地层损失,提出了一种考虑了DOT工法施工特点的半理论半经验计算模型。用该模型采用peck法进行了地表沉降的计算,并同工程实测数据进行了对比。结果表明,实测结果同模型预测相对误差可以控制在工程允许的范围内。
The article puts forward a semi-empirical and semi-theoretical calculation model considering the characteristics of DOT construction method to calculate the ground loss caused by DOT tunneling from the viewpoint of engineering practices.This mode uses peck method to calculate the surface settlement,and contrasts with the engineering measured data.The result shows that the relative error of the measured data and the model prediction can be controlled within the allowed limits of project.
