Abstract: The geographical position of our country -- China -- behaves the conditions to form glacier ice, lake ice, river ice and sea ice. In this paper the general situations of specialists, organizations and working achievements for research river ice and lake ice are introduced firstly. There are numbers of specialists flocking together at Lanzhou Institute of Glaciology and Geocryology. One of their specialty is the research of glacier ice, especially the ice core collected from Law Deme of Antarctic, which was the cooperated project with Australian specialists. They investigated the relation between C-axis and depth of ice layer, the behavior of creep accompanied with fatigue in laboratory detaily. As for sea ice there are three researching groups existing around Bohai Sea. Professors and skilled people of Tianjin University researched the static and dynamic response of offshore structure interacted with sea ice. There is a Research Division of Ice Mechanics belonging to Dalian University of Technology (i. e. Dalian Institute of Technology). Its professors, lecturers, engineers and technicians researched the compressive, tensile, bending strength of Bohai Sea ice and their strain-rate sensitivity and scale effect, the fracture toughness of mode I, II and mixed mode, especially the fracture toughness by using compact compression lest specimen (CCTS). The Institute of Marine Environmental Protection, which subordinated to state Bureau of Oceanic Administration, has a research division for sea ice. Several years ago they engaged in experimental tests on compressive strength of sea ice picked from Bayu Harbour, the bending strength and fracture toughness were The project supported by National Natural Science Foundation of China.
