The invention provides a method for laying geotextile underwater, which includes steps of: 1. berthing the laying ship along a dike axis; 2, fastening the geotextile to be layed with rope; 3. pulling the pulley set to coil the geotextile; 4. nailing two positioning steel pipes close to the ship edge; 5. putting the geotextile down close to the steel pipes; 6. laying the geotextile coil beneath water, pressing the geotextile edge with a stone bag, then moving the ship; 7. dropping a stone bag upon a determined distance of moving; 8. recycling geotextile tube in the water; 9. pressing the terminal edge of the geotextile with a stone bag, and laying the next block of geotextile. The method for laying geotextile underwater is capable of uniformly distributing gravity onto the draining board of the lower layer, and the phenomenon of draining board break due to partially bearing too much force. The method for layer geotextile underwater is further capable of effectively reducing maintenance frequency of the outer port channel, so as to reduce maintenance cost of the port.
