Abstract: The traditional grouting engineering design method can not meet the requirements of information development in engineering construction.In order to realize the visual display, rapid expression and intelligent construction of grouting engineering, it is necessary to develop parametric grouting design methods and results.This paper put forward the modeling idea of “whole-local-whole” to establish parametric design model, that is, the grouting engineering system is first decomposed into single grouting holes and coded, then the geometric model of each grouting hole is constructed separately, and the characteristics of grouting process attributes are added, finally the parametric design model of grouting is integrated.By analyzing the structural characteristics, design and construction requirements of a single grouting hole, 8 parameters such as hole coordinates, are proposed to represent the geometric characteristics of the grouting hole, and 10 other parameters such as grouting method are used to represent the grouting process properties, and the acquisition method of each parameter is studied.The research results are applied in the grouting project of the Wudongde Hydropower Station, realizing 3D visualization of grouting and improving the intelligent level of the grouting project construction.
