摘要
随着城市建设与经济的发展,各种地下工程应运而生。顶管施工是隧道施工中最常见的方式之一,但顶管施工对临近桩基的影响已成为不可忽视的课题。基于顶管施工临近桩基,进行模型试验,为理论分析地层参数的取值提供参考。通过模型试验和数值模拟进行互相对比,从而得到顶管施工对临近桩基的影响规律。这对类似工程具有较高的参考价值。
With the development of urban construction and economy,various underground projects emerge as the times require.Pipe jacking construction is one of the most common ways in tunnel construction,but the influence of pipe jacking construction on the nearby pile foundation has become a topic that cannot be ignored.Based on the construction of pipe jacking near the pile foundation,model tests are carried out to provide reference for theoretical analysis of the value of formation parameters.Through the comparison of model test and numerical simulation,the influence law of pipe jacking construction on the nearby pile foundation is obtained.It has a high reference value for similar projects.
