综合勘探方法在断层的应用.doc

田阳华润建设场地电法勘探资料的解释 学生：李云超 指导教师：单娜琳 摘要：断层活动形成的破碎带，多数会与围岩产生一定物理电性差异。通常为电阻率减小，表现出低阻异常。但是隐伏断层本身存在一定的复杂性，再加上一些干扰因素的影响，通常单一的勘探手段难以准确的找到断层位置。而针对不同环境，不同要求，以及不同规模的浅层断层破碎带的勘探，现已总结了许多种综合物探手段。 本文在田阳那坡尝试了运用高密度电阻率法与瞬变电磁法相互配合验证的方式，来勘探地下隐藏的断层破碎带。全文首先讨论了高密度电法以及瞬变电磁法的原理以及特点，再对工区场地地质状况，以及断层地球物理特征进行了描述。从而阐述了本次勘探方法选取的合理性。最后，讲解了资料处理的过程，并最终对资料进行了综合解释，给出断层大概位置。 本次勘探结果显示，在对工区资料进行详细了解的基础上，针对勘探目标的特性，合理的选择勘探方法，能够有效提高物探成果的可靠性和实用性The interpretation of electrical exploration data about Huarun Construction site in Tianyang Student：LI Yun-chao Teacher: SHAN Na-lin Abstract：The differences between fracture zone and wall rock about the physical characteristics，usually for lower-resistivity layer. However, the existence of hidden faults is also a certain degree of complexity, combined with a number of interfering factors; a single exploration usually means that it is difficult to find accurate fault location. The shallow fault broken exploration for different environment, different requirements, as well as different sizes, have been summed up the means of many types of geophysical exploration. In this paper, a different method has been tried in Tianyang Napo. This method used the high density resistivity method with the transient electro-magnetic methods (TEM) to the underground exploration of the fault fracture zone. The full text of the first discussed the principles and characteristics of both high density resistivity method and TEM. Then geological conditions of the work area have been described in detail, as well as the geophysical characteristics of fault. So expound the rationality in this way. In the article, the final, we talk about data processing process and explained synthesis of information. The exploration results indicate that Good exploration results need for detailed planning. Including a detailed understanding the information of the work area and choosing a reasonable prospecting method which base on the characteristics of exploration target. All of these can effectively improve
