【摘要】 铜川市地处陕北黄土高原区，受自然因素和人为因素的双重影响，各类地质灾害频繁发生并严重制约了该地区社会、经济和环境的可持续发展。本文运用地质学、工程力学和开采沉陷学等理论，对区内斜坡地质灾害和矿区采空塌陷的灾变机理进行了分析，探讨了影响其灾变过程的主要因素。在此基础上，应用模糊综合评判和概率积分法分别对斜坡地质灾害和矿区采空塌陷的稳定性进行了半定量的评价，其结果为采取合理的防治措施提供科学依据；同时也为该地区地质灾害的综合区划研究提供了一个重要的参考指标。研究区地质灾害的区划研究非常有限，研究成果主要局限于矿区。为满足全区实施防灾减灾战略的需要，本文在充分收集近年来铜川市各区县灾情资料的基础上，以受灾人口、破坏房屋、受灾面积、直接经济损失为参评指标，以铜川所辖区县为评价对象，利用模糊灰色聚类的数学方法将整个地区划分为极重灾区、重灾区和中灾区三大片区。为了更客观的反映实际灾情，本文利用稳定性评价的研究结果得到各区县不稳定地质灾害体的发育密度指标，对两个极重灾区进行了二级区划。综合区划研究的结果与各区县实际灾情基本吻合，证明所用区划方法是科学可行的。文章最后就研究区地质灾害的防治对策从技术和管理两方面提出了建议，对当地的防灾减灾工作具有一定的参考价值。本文突出了在定性分析的基础上使评价过程定量化的原则，将一系列的数学理论与实践应用相结合，具有一定的理论意义和现实意义。更多还原

【Abstract】 Being situated in the loess plateau area, TongChuan is greatly influenced by natural factors and artificial factors and all kinds of geologic disasters have happened, which severely restrict the sustainable development of regional society, economy and environment of TongChuan. This article applies geology engineering mechanics and the science of mining subsidence to analysis the deformation mechanism of the slope geologic disaster and the mining subsidence in TongChuan district. It explores the main factors that influence the process of the disasters. Based on the above-mentioned research, it uses the fuzzy pattern recognition theory and rate integral calculus method to research the stability of them. The results help people to adopt reasonable prevention measures; at the same time, they are used to study the comprehensive regionalization of geologic disasters.In TongChuan the study about geologic disasters is very limited. It mainly studied the mineral area. In order to meet the need of the disastrous prevention for the whole region, this article adopts the disastrous indexes which are the population, the buildings, the tillable field endangered by the disasters and the direct economy loses and utilizes grey clustering theory to divide the region into three areas. This article uses the growth density index of the unstable geologic disasters in all the counties to distinguish the two heavy disaster areas. The study results are satisfied with the real disastrous conditions of the each county. At last, it offers some suggestions about technology and management that prevent geologic disasters and they would be helpful for the decrease of the geologic disastrous loss. The importance of this article is the quantitative analysis principle during evaluation process based on the qualitative analysis. It puts a series of mathematical theories into practice. This paper has some theoretical value and practical value.更多还原
