【Abstract】 To overcome some principal drawbacks in the waterproofing of composite linings, this paper studies the crucial techniques of partitioning waterproofing with membranes by carrying out a model test and to evaluate the waterproofing effect. As a result, it puts forward the principles of partitioning waterproofing, technical parameters and the injection parameters for arch crown that can guarantee the regional watertight. Yangzong tunnel was chosen as an engineering example with partitioning waterproofing techniques adopted, good results of watertight and impermeability were attained in the tunnel on its water-soaked sections.更多还原
