This invention discloses a construction method and system for full-casing cast-in-place piles on the side of a subway, specifically relating to the field of foundation engineering technology for construction near subway protection zones. It addresses the problem that existing full-casing techniques are insufficient to withstand the dynamic pore water pressure coupling caused by subway operation, leading to the risk of borehole instability. By simultaneously monitoring the ground pressure inside the casing and on the tunnel side, the method assesses the disturbance propagation intensity and identifies abnormal fluctuations inside the casing based on the tunnel side pressure. When an anomaly is detected, coupled modal analysis is performed on the data from both to extract dynamic modal parameters, thereby assessing the cumulative disturbance effect of subway loads. Finally, based on the assessment results, active pressure compensation is initiated during borehole formation, and the effect is verified after compensation. This achieves real-time perception, mechanism diagnosis, and active control of dynamic operational disturbances from the subway, improving the safety and reliability of full-casing borehole formation in sensitive environments.
