摘　　要：河北平原地裂缝在时空上呈现递增和扩展的趋势,地裂缝往往是诸多因素共同作用的结果。地裂缝的成因总体遵循构造运动主导,地形地貌、土体岩性、降水作用为条件产生。地裂缝的破坏力是持续和长久的,对其形成机制和现状的研究具有非常实用的价值。The ground fissures in Hebei plain showed a trend of increasing and extended in time and space. As we known, a variety of factors result in the ground fissure. Its causes generally follow a rule, which is that the tectonic movement is principal, next is the landform, soil features, and precipitation effect, as the secondary conditions. The destructive of the ground fissure is a continuous and long-term, so the study on its formation mechanism and the status is of great practical values.
