| Abstract: | In order to increase the pile load capacity and reduce pile foundation settlement,the post grouting technique for cast-in-place pile may be used.Based on the prevailing geotechnical condition of Ningbo region and a specific construction project,a test is conducted to compare the effect of cast-in-place piles with and without jet grouting.The result indicates that the load capacity of individual pile may increase by from 22%to 29.4%after a jet grouting process,producing the remarkable economic benefit from adopting the proposed technique. |
