Through the simulation of deep excavation, the mechanism of load transfer and settlement of the pile loaded after deep excavation are studied. Then, parametric research of pile testing used steel bar meter suggested in this paper are conducted，the results show that theeffective pile length,reinforcement meter loss ratio is small,and the excavation depth increases, the loss ratio change at the level of 10% to 15%. It is suggested that the bearing capacity of uplift piles after excavation can have a reduction in 10% to 15% in experience according to the suggested test pile used steel bar meter.

The major monitoring parameters included surface acceleration , deep layered acceleration and layered settlement. Based on analysis of layered settlements and surface vibration spectrum, conclusions were drawn regarding the principles of surface vibration and the degree of disturbance to mucky silty clay caused by the drilling process. The environmental impact induced by drilling construction was properly evaluated. This study shows that vibration caused by drilling decreases rapidly in surface and formation. The measured vibration frequencies are mainly in high-frequency side. Vibration caused by drilling did not resonate with building, and hence the impact on building was limited. Ground settlements were mainly caused by vibration-subsidence of soft layers. Differential settlement of the building is less than the regulatory requirements.
