The Bearing Capacity Research And Settlement Prediction Of The Post-grouting Bored Pile

Bored pile with grout pour technique is a kind new process which is based on cast-in situ bored pile technique. It overcome the flaw of the cast-in-situ bored pile. It can increase the bearing capacity of the cast-in-situ bored pile. It has important actual meaning ,and it can bring a large economic benefit.This paper introduces the grouting mechanism and construction technology of the bored pile with grout pour . then show the bearing capacity of the gravel and show the bearing capacity of HangZhou. then do the further research of the pile bearing capacity effects through the static load test of the test pile.Make the pile simulation with the FLAC3D .then take the stress analysis. At the same time , compare the calculation result with the experimental result. Verify the accuracy and reliability of the bearing capacity formula.Training the existing engineering data with the BP neural network . Then get the relationship model about the bearing capacity and settlement. Predict the settlement under the different bearing capacity , with the model. It can be used into the projectto make the theoretical predictions ultimate bearing capacity of the project.
