Abstract Ground settlement induced by subway tunneling is becoming one of the main causes of ground subsidence. It strongly affects the serviceability of superstructures and pipelines around the subway tunnel. Therefore，it is very important to predict the settlement accurately. Numerical simulation was conducted to investigate the influence of grouting pressure and working face thrust force on the ground settlement caused by tunneling. The grouting pressure and working face thrust force were normalized using the gravity of the overburden soil and the lateral static earth pressure，respectively. Based on the equivalent ground loss method proposed by K. M. Lee et al.，procedures considering the construction effect during shield tunneling were put forward to estimate the ground settlement. Comparison numerical and calculated results demonstrates the effectiveness of the proposed method.
