由于金川水电站混凝土趾板基础强、弱卸荷岩体裂隙发育,透水性较强,可供借鉴的类似工程经验很少,主要针对试验中的帷幕试验进行分析研究,通过固结、帷幕试验,使金川水电站两岸卸荷岩体试验区内浅表及较深层岩体的防渗及岩体的整体性、均一性得到了显著提高,满足了设计的各项指标要求,可直接指导金川水电站两岸卸荷岩体固结、帷幕施工,以解决卸荷岩体较深层岩体的渗漏控制问题。
由于金川水電站混凝土趾闆基礎彊、弱卸荷巖體裂隙髮育,透水性較彊,可供藉鑒的類似工程經驗很少,主要針對試驗中的帷幕試驗進行分析研究,通過固結、帷幕試驗,使金川水電站兩岸卸荷巖體試驗區內淺錶及較深層巖體的防滲及巖體的整體性、均一性得到瞭顯著提高,滿足瞭設計的各項指標要求,可直接指導金川水電站兩岸卸荷巖體固結、帷幕施工,以解決卸荷巖體較深層巖體的滲漏控製問題。

The Jinchuan hydroelectric power station locates in strong and weak unloading rock. Because of the development of the strong and weak unloading rock and high permeability, and rarely projects can be referred, this paper analyzes and researches the experiment of the curtain grouting. The experimental research on the consolidation grouting and curtain grouting greatly improves the integrity and homogeneity of the shallow and deeper surface’ s seepage of the test area, which satisfies the design. It can guide the construction of the consolidation grouting and curtain grouting in the station directly to solve leakage problem in deeply unloading rock.
