利用大地电磁三维反演方法获得二维剖面附近三维电阻率结构的可行性
大地电磁反演 二维 三维 张量数据
2011/8/9
大地电磁野外实测数据目前大多为二维剖面数据.如何反演这些二维剖面数据获得较为接近实际地电情况的结果,是多数大地电磁工作者关心的问题.我们通过对理论模型的三维响应进行分析和对合成数据及实测资料的反演结果进行对比研究,讨论了利用三维反演的方法来获得大地电磁二维剖面附近三维电阻率结构的可行性.结果表明:可用三维反演的方法来解释二维剖面数据.对大地电磁二维剖面的张量数据进行三维反演,不仅可以沿剖面获得较好...
基于野外调查、测绘、现场、室内实验及收集大量的滑坡位移观测曲线，结果发现：这些曲线呈振荡状。分析认为这种振荡曲线与地球自身的脉动有关，它是由地球脉动、高渗透水力坡降和大的滑体剪切作用叠加而成的一种呈非平衡态的复杂运动。从理论上分析了黄土遇水后Ｃ，ψ值降低的原因（即黄土颗粒之间粘结键和摩擦力大大降低）。

高密度电法 接地电阻 视电阻率
2010/8/16
首先在同一实验场地进行接地电阻均匀与非均匀情况下的电法勘探对比试验，讨论在地下各层视电阻率
变化率及接地电阻对视电阻率的影响灵敏度；通过逐个舍弃电极实验，比较舍弃不均匀电极的反演剖面图，确定出合理摈弃非均匀接地电阻数量的范围；最后在实例电法测量中运用舍弃非均匀电阻方法有效阻止了异常接地电阻的反演畸变，提出了合理舍弃高阻电极测量数据的实测视电阻率资料处理方法。
坑道内赤道偶极电阻率测深的可行性
坑道 赤道偶极装置 电阻率测深 有限元
2009/8/31
对坑道内赤道偶极装置电阻率测深的可行性进行研究。分别在4个坑道面上布设测线,利用赤道偶极电阻率测深装置对坑道周围介质进行探测;采用有限单元法对坑道内赤道偶极装置电阻率测深进行正演计算。计算结果表明,对于单个地质体,坑道内任一断面的视电阻率异常均与其相邻的2个坑道面上的测深断面异常性质相反,而与坑道对面的测深断面异常性质相似;当坑道面外侧存在多个地质体时,各坑道面上的测深断面均不能将其有效区分。根据...
