Based on the construction of connected aisle of shield tunnel in Nanchang rail transit line 1 , construction schemes of grouting pile reinforcement in watery complex strata are summarized. Problems of water inflow and sand inflow during the construction of connected aisle are analyzed and corresponding disposal program is put forward, which includes grouting reinforcement of soil and dewatering with dewatering well. Actual status and earth’s surface monitoring results of the construction site show that such disposal program can ensure the safe and smooth construction of connected aisle under this strata condition.
