| Abstract: | On the basis of observation of pressure grouting experiment at the subway tunnel site,it studies the mechanism of pressure grouting and discusses the key points in design and construction and makes the comparison of the calculation methods of tunnel heave post-grouting.By use of the field measurement data of tunnel deformation,the empirical formula of equivalent grouting pressure is determined through the feedback analysis.The formula will guide the design and construction of pressure grouting beneath the s... |
