    摘要:

    通过沿地裂缝展布区进行详细的地质调查和地质填图,分析清徐地裂缝灾害的主要特点。根据调查结果,按照通用受灾体经济损失计算方法,折算出地裂缝对清徐造成的直接经济损失。结果表明:清徐地裂缝灾害有如下主要特点:(1).地裂缝灾害的衡生性;(2).地裂缝灾害的三维破坏;(3).地裂缝破坏的有限性;(4).地裂缝成灾过程的渐发性。清徐构造地裂缝造成1 973间房屋严重破坏,3 460间房屋中等破坏,4 050间房屋轻微破坏,房屋经济损失约1.168 65亿元;约使1 090余亩耕地失去了灌溉功能(由水浇地变为旱地或成为荒地),耕地经济损失约218万元;对公路造成三处破坏段,道路经济损失约870万元。清徐构造地裂缝带造成的直接经济损失约1.278 45亿元。

    Abstract:

    We carried out a detailed geological survey and mapping along the ground fissures distribution area in Shanxi Qingxu and rich databases were stored for the future study of the geological structure and ground fissure. According to the survey, the direct economic losses caused by the ground fissures were converted with the universal affected body economic loss calculation method.The results show that the main features of the ground fissure disaster in Qingxu are as follows:(1) horizontal feature; (2) dimensional damage;(3)limited destruction range; 4.gradual process. Construction ground fissures caused 1,973 houses seriously damaged 3,460 houses medium damaged, 4 050 houses minor damaged, and housing economic losses were about 1.168 65 billion in Qingxu. Approximately 1 090 acres of arable land lost irrigation functions and become dry land or wasted land, and arable land economic losses were about 2.18 million yuan. Ground fissures caused highway damage in three places and the road economic losses were about 8.7 million yuan.In general,Direct economic losses caused by the construction ground fissures were approximately 1.278 45 billion in Qingxu.
