Abstract: A lot of ground fissures have occurred in Hebei Plain since 1980s. Some of them have extensive damage to the buildings and roads, and have serious damage to the people’s life and property. The fault creep type ground fissures are characterized by long stretch, great depth, serious destruction, and difficult prevention and control. It is suggested that more attention should be paid to the fault creep type ground fissures which have important significance in the research and control of ground fissures in Hebei Plain. Based on wide filed investigations, two typical fault creep type ground fissures (the Longyao and Xin-An-Shen-Rao) are selected from more than 800 ground fissures. The genesis is preliminary analyzed according to the comprehensive method of geophysical prospecting, trenching and other exploration. It is proposed that the fault creep type ground fissures are controlled by fault activities of study area; the deep tectonic activities provide dynamic foundation for the formation of ground fissures; the activities of ground and surface water promote the opening and development of ground fissures.
