| 摘 要： | 河流峡谷地区特有的地形地貌、地质特征等自然、地质条件使得这些地区的地下水温度场表现出了异常的现象。以金沙江上游溪洛渡水电站峡谷区为例,采用数值模拟、类比和回归等方法对电站峡谷区地下水温度场作了系统的分析,探讨了河流峡谷区地下水温度场异常的机理,实例分析表明:溪洛渡峡谷区地下水温度异常是由于区域循环地下水流经过深部加温后在排泄处表现出来的正常现象,并非活动构造形成的,在该区选址建坝是可行的。

| Abstract: | The groundwater temperature field shows some abnormal phenomena due to special topographic and geormrphic conditions and geologic characteristics in canyon areas.Taking groundwater temperature field in canyon areas at Xiluodu hydroplant as an example,the groundwater temperature field is analyzed systematically through the numerical simulation,the analogy and the regression analysis method.And then,the abnormal mechanism of groundwater temperature field in canyon areas is discussed.From the examples analysis,it is concluded that as region groundwater flow in deep circulation is warmed through deep parts,the abnormity of the groundwater temperature in Xiluodu canyon areas is normal phenomena displayed in drainage region.It is not made by active tectonics.Therefore,the dam location selected in here is feasible. |
