| Abstract:In this paper, the mechanism of high pressure jet grouting has been introduced. Excess pore water pressure generated by high pressure jet grouting during construction was investigated. On the basis of cavity expansion theory, the formulae of excess pore water pressure has been proposed, and the stress and strain of soil had been analyzed. Through an engineering example, the formulae of excess pore water pressure was verified. |
