摘要：
Ground movement is an important problem for the construction using Horizontal Twin-jet Grouting Method (HTGM), and it is affected by many factors. In this paper, Finite Element Method (FEM) is employed to analyze the ground movement during the construction, and two models are selected for analysis, in which one model is to analyze the condition for construction of one column, and the other model is to analyze the condition for construction of a few columns. In this analysis, jetting pressure, retrieving rate of the rod, and number of the columns are mainly considered. Based on the analysis, in order to alleviate the effect on surroundings, construction parameters such as jetting pressure and retrieving rate of the rod were suggested.
