【摘要】 本文论述了地裂缝灾害的一般特点，从四个方面对地裂缝灾害的评价方法进行了较为全面的论述。提出了地裂发生概率函数ＰＧＦ、地裂缝对承灾对象影响概率函数ＰＧＯ、地裂缝综合公里破坏系数、地裂缝综合公里损失系数等评价指标，并根据地裂缝的空间形态及影响宽度进行了分类，对地裂缝的危险性进行了分级。最后指出了地裂缝灾害防灾减灾的一般对策。更多还原

【Abstract】 This paper overall expounded the ordinary characters of geofracture hazard and evaluation method of geofracture hazard from 4 aspects. The evaluation indexes-probabilistic function PGF of geofracture happening. probabilistic function PGO of influence of geofracture on hazard-bearing objective, synthetic kilometer damage factor, and synthetic kilometer loss factor of geofracture were put forward. And they were classified according to its space morphometry and influence width. The risk of geofracture has been graded,too. Finally,the ordinary countermeasures of prevention and decrease of geofracture were pointed out.更多还原
