ABSTRACT
Soil parameters along the heading direction are subjected to spatial variability during shield
construction, so grouting pressure requires constant adjustment to ensure ground stress sta-
bility. This causes grouting pressure to fluctuate around the design pressure/curve. There-
fore, the influence of the grouting pressure volatility on the adjacent loaded-pile foundation
should be considered in shield tunneling. In this study, a refined numerical simulation of
the shield construction process is conducted using the Fast Lagrangian Analysis of Continua
in Three Dimensions (FLAC3D) software. A total of 300 groups of grouting pressure pa-
rameters with a skewed normal distribution are input into the numerical model. Then, the
influence of the construction parameter uncertainty on the adjacent loaded-pile foundation
is analyzed. Finally, the back analysis method is conducted based on the monitored data to
evaluate how the construction process affects the pile foundation. The calculation results are
compared with those of the traditional finite element method. The results indicate that in
the tunneling process, the grouting pressure fluctuation greatly affects the additional bend-
ing moment of the adjacent pile foundation. Under the influence of the grouting pressure,
the additional axial force and additional bending moment of the pile foundation also follow
the skewed normal distribution. The back analysis results of the pile foundation are greater
than those of the typical numerical method by about 60% 100%, that is using the back
analysis calculation results to evaluate the pile foundation additional response can reduce
the risk.
