DEVELOPMENTS AND QUALITY SAFEGUARDS IN IMMERSED TUNNEL TECHNIQUE

Over the past decade, quality assurance has become increasingly important in immersed tube tunnelling. A guarantee of meeting quality standards has become paramount in obtaining financing for high-risk tunnelling projects. To assist in designing such works to guarantee durability and watertightness, the Dutch ministry of public works has begun a project to inspect thoroughly and record information about various civil engineering projects, including immersed tunnels. A computerized program will describe problems with quality, define repair needs and link this information to repair and maintenance costs. This paper discusses ways to control the concrete-hardening process (a major concern in assuring quality in tunnels) through computer-assisted engineering programs in order to obtain a high-quality product. Advantages of computer-aided design systems are addressed, as are future needs with regard to solving problems associated with tunnel leakage.(a)
