The technological progress of geotube engineering in China was demonstrated through reviewing the representative geotube dams since 1980s. The development of project design, process equipment and technical measures was analyzed and the results of fundamental research for engineering applications were also summarized. Taken the widely used high strength elliptical geotubes abroad as reference, simplified ordinary strength flat geotubes were developed in China. They have been important components in the construction of huge infrastructures such as fresh water reservoirs in estuaries, deep-draft channel improvement, harbors, airports, dikes in coastal areas, wave breakers, beach reclamation, etc. The regions of geotube dam construction range from intertidal zones to complex areas with deep tidal currents. The construction operation of geotube dams has been changed mainly from manpower to equipment and until recently underwater construction in complex deep-water regions can be accomplished by multi-integrated equipment. The encircled area by geotube dams is becoming larger and super large closure gaps can be closed successfully.
