U.S. – China Collaborative Research Directions on Trenchless Technology and Critical Underground Infrastructure Issues

There is no doubt that growth in human population and economic development strain the world's finite resources such as land, water, food, and energy. To maintain and improve quality of life, we need sustainable technologies and asset management strategies that meet human needs for limited natural resources. The lack of technical resources and limited experience in developing new and emerging underground technologies has created urgent needs for research, development and outreach throughout the world. An important element in addressing the underground infrastructure challenges is collaboration among international researchers, specifically from the major countries and world powers, where the problems and possible solutions may be addressed. The role of universities in bringing these stakeholders together is particularly important. Universities provide insights, conduct research, disseminate research findings, facilitate cooperation and development and provide educational opportunities for current and future professionals. Founded by National Science Foundation, The University of Texas at Arlington and the China University of Geosciences, this workshop brought together research expertise across various disciplines to utilize best resources relevant to solving underground infrastructure problems. The event provided an opportunity for researchers from both countries to target critical areas specific for each country, and capitalize on local recourses. The critical technologies identified by researchers focused on trenchless methods, utility locating, freight pipelines, and asset management. This workshop was an excellent opportunity to address asset management and sustainability of lifeline systems and develop collaboration strategies and joint research programs. The workshop and site visits were held in October 10–15, 2007, and included 14 U.S. professors, researchers, and representatives of Chinese universities, municipalities, government agencies and industries. This paper will present details of this workshop, results obtained, and directions for future efforts.
