Quality certification considerations for a thin-sized concrete seepage-control wall of river dyke

Based on geological data,a seepage model was created in accordance with identical boundary conditions. The consistency of between mathematical model and seepage one was verified through special calculations and testing. Seepage testing was carried out by simulating different flood levels to determine appropriated parameters for water injection testing. With these parameters as a base,some typical experimental sections were selected for injection testing. From the results of testing,the wall's seepage-control effectiveness and related volume of work under different flood levels were analyzed and evaluated taking into account the data resulted from conventional methods. The paper discusses the quality testing and inspection methods of wall and puts forward,first in practice,the idea of equivalent level. The application of this type wall to another similar project (Xinlonggong project located in lower reach of the river) has shown the feasibility for evaluating the quality of a thin-sized concrete seepage-control wall.
