Abstract

Abstract

The deformation laws of soil caused by grouting and grouting efficiency with times and space were lack of systematic theoretical research, which hindered the application of grouting in accurate deformation control of proximity construction. Based on the field test, the variation laws of soil deformation and grouting efficiency with time and space were systematically studied by using the numerical simulation method of fluid-solid coupling. Simultaneously, the effects of grouting parameters such as grouting volume, grouting space and grouting depth on soil deformation and grouting efficiency were considered. And based on the study, some suggestions on grouting deformation control were put forward. The study indicated that when it was necessary to control subsidence of the ground or tunnels, it was suggested that the top of the grouted body should be flush with the target object. When it was necessary to control heave of the ground or tunnels, it was recommended that the bottom of the grouted body be flush with the target object. With the increase of grouting space, the horizontal and vertical displacement of soil and the grouting efficiency of horizontal displacement decreased rapidly. In order to ensure the deformation effect caused by grouting, the grouting distance should be not to long.
