| 摘 要： | 地下工程涌突水是影响工程施工及运行的一个重要问题,目前对水电站地下工程涌突水危险性评价的研究较少。本文以自一里水电站为例,参考已有且较为完善的岩溶隧道涌突水及非可溶岩长深隧道涌突水的危险性评价方法,从地下水通道和地下水来源(补给)两个涌突水控制因素入手,综合分析各项要素,对自一里电站地下硐室的涌突水危险性进行初步分区。结果表明:自一里电站厂址区整体涌突水危险性较低,但在局部地段有发生涌水的可能。厂址区硐室按照涌突水危险性高低可分为较高危险区、中等危险区和低危险区。

| Abstract: | This paper has a discussion on influence of bursting surge on project construction by the example of construction of the Ziyili Power Station, referring to the existing and perfect evaluation system of the karst tunnel surge and non-soluble rock and long deep tunnel surge, and starting from the two water control factors of groundwater channel and groundwater source. The results show that risk of the overall surge at the site of the Ziyili power station is low, but there is still the possibility of bursting surge in the local area. The room site can be roughly divided into high danger zone, medium danger zone and low danger area according to the risk of surge water. |
