Abstract:
Basing on the assumptions of exponential fluid and narrow plate model, formula of climbing height in base post-grouting is deduced. It is shown that the climbing height is mainly related to grouting pressure, pile length, pile diameter and mudcake thickness. The climbing height increases with the decrease of soil deformation modulus and pile length. And it increases with the increase of grouting pressure and mudcake thickness. At last, the formula of climbing height is verified by case study.
Key words: post grouting, exponential fluid, climbing height, mudcake
