摘要：
This study developed tunneling influence zones for nearby pile foundations in Bangkok soft soil using the numerical analysis results. The analyses were conducted by means of three dimensional simulation of interaction between an existing pile foundation and tunnel construction. Both the shallow tunneling (long pile) and deep tunneling (short pile) conditions are separately investigated and the zones of influence are suggested. By combining the zones of influence from both conditions, the tunneling influence zone for adjacent existing pile foundation in soft soil can be obtained. Based on the ground condition, geometries of the pile and the tunnel, tunnel construction method, and evaluated criteria considered in this study, the unique significant zones of influence for various conditions can be identified. The obtained zones are also discussed with those suggested in previous study.
