A method to measure several forces exciting a structure simultaneously is proposed. It is based on the theorem of exchange energies which can be considered as a multiple application of the reciprocity principle. First experiments using the method showed measure errors to be only a few dB. The calculated phases agreed reasonably well with the measured data. It is recommended to use more than the minimum number of measuring points to increase the reliability of the method.

Geoelectricity variations are complicated in igneous rock area, where the conditions of horizontal bedded media cannot be met and the quantitative interpretation of electrical sounding data is difficult. For the first time, we have tried two-dimensional interpretation of electrical sounding in northwestern sector of the Yangxin rock mass and achieved good re-sults. In the two-dimensional interpretation, we adopt the point source finite-element method and the reciprocity principle which can lighten the calculation burden. The two-dimensional interpretation can be divided into four steps: 1. Forming initial geoelectric section model, after the one-dimensional interpretation generally; 3. Carrying out forward calculation with computer and repeating interactive modification until sat-isfactory results have been obtained; 4. Geological interpretation for calculation results. Compared with one-dimensional interpretation, the two-dimensional interpretation of electrical sounding can help us to study geological structures and boundaries more distinctly and accurately.

火成岩分布区,地电变化复杂,不能满足水平层状介质条件,造成电测深资料定量解释困难。我们首次在阳新岩体西北段进行了电测深二维解释的尝试,并取得了较好效果。二维解释是采用点源有限单元法,为减少计算量,利用了互换原理。二维解释工作可分为四个阶段:(1)构组初始地电断面模型,通常在一维解释成果基础上进行,(2)部分:将地电断面划分为计算小单元;(3)用计算机进行正演计算,不断迭代修改,直至得到满意的给果;(4)计算结果的地质解释。与一维解释结果对比,用电测深二维解释方法研究剖面的构造特征、划定地质界线比较清晰准确。
