| 摘 要： | 井孔水位对地壳应力应变的反映能力取决于井－含水层系统的多方面条件，观测井的直径大小是其中之一。在云峰井进行的变径观测结果。水位变动段的直径由１１８ｍｍ缩至８０ｍｍ之后，水位固体潮井系数明显变大，水位记震能力有显著提高，水位气压系数也有所增大。这样的事实表明，缩小水位变动段的井径是提高水位映震能力的有效途径之一。

| Abstract: | The capability of well water level to reflect the crustal stress-strain depends on various conditions of the well-aquifer system, among which the borehole diameters of the observation wells is one important factor. The results obtained from observation by changing borehole diameters in Yunfeng well show that the well-tide coefficient of water level solid tide obviously increased, the capacity of water level to record seismicty and water level pressure coefficient is also increased with decrease of the borehole diameters pf observation well from 118 mm to 80 mm.So, it could be considered that the diameter reduction of the borehole in which water level changes, is one of the effective approaches to increase the capacity of water level to reflect seismicity. |
