熵权模糊聚类信息流法在渗漏探测中的应用
|
摘要
针对小浪底水库左坝肩渗漏问题,采用熵权模糊聚类信息流法对采集的14个样本进行分析,以确定渗漏水的补给来源,并结合温度和电导探测、连通试验等方法确定集中渗漏通道。结果表明:1号排水洞3号孔、1号排水洞35号孔、2号排水洞28号顶孔、2号排水洞94号顶孔、4号排水洞28号底孔、30号排水洞D-18号孔、30号排水洞RD-7号孔中的水由浅层库水补给;30号排水洞D-133号孔中的水由深层库水补给;30号排水洞D-194号孔中的水由深层库水、尾水、地下水补给;30号排水洞RD-37号孔中的水由地下水和尾水补给。通过对集中渗漏通道实施灌浆补强、断层封堵等防渗加固措施,各级水位下总排水量均比以前减少,减少幅度为25%~40%,因此熵权模糊聚类信息流法用于判别渗漏水的补给来源是行之有效的。
To investigate groundwater leakage from the left dam abutment of the Xiaolangdi Reservoir,an information flow method based on fuzzy clustering and entropy weights was used to determine the supply sources of leakage water according to analysis of 14 samples.Meanwhile,temperature and electric conductivity detection and interconnection testing were used to ascertain the concentrated leakage channels.The results show that there were different supply sources of leakage water: shallow reservoir water(borehole 3 in drainage tunnel 1,borehole 35 in drainage tunnel 1,top hole 28 in drainage tunnel 2,top hole 94 in drainage tunnel 2,borehole 28 in drainage tunnel 4,borehole D-18 in drainage tunnel 30,and borehole RD-7 in drainage tunnel 30);deep reservoir water(borehole D-133 in drainage tunnel 30);the mixture of deep reservoir water,tail water,and local groundwater(borehole D-194 in drainage tunnel 30);and the mixture of tail water and local groundwater(borehole RD-37 in drainage tunnel 30).After implementation of some seepage control and reinforcement measures,such as curtain grouting and fault plugging,the total leakage flux at different reservoir water levels was reduced by a range of 25% to 40%.Therefore,the proposed information flow method is effective in determining the supply source of leakage water.
