锦屏一级水电站地下厂房洞室群围岩变形较大,松弛圈深度偏大,且进一步向洞室深部发展,需进行有效控制.在对围岩松弛圈变形机理进行系统分析的基础上,结合有关支护的咨询意见,有针对性地提出加固处理措施,对保证洞室稳定和施工安全起到积极的作用,也为类似工程积累了一定经验.
錦屏一級水電站地下廠房洞室群圍巖變形較大,鬆弛圈深度偏大,且進一步嚮洞室深部髮展,需進行有效控製.在對圍巖鬆弛圈變形機理進行繫統分析的基礎上,結閤有關支護的咨詢意見,有針對性地提齣加固處理措施,對保證洞室穩定和施工安全起到積極的作用,也為類似工程積纍瞭一定經驗.

The deformations of the surrounding rocks of the caverns for the underground powerhouse of Jinping Hydropower Station I are large with greater depths of relaxation zones and trend to develop into the depths of the caverns; on which the effective control must be made. Based on a systematic analysis on the deformation mechanism of the relaxation zone, the strengthening treatment measure is pertinently put forward herein with the references from the relevant consulting suggestions on the supporting measure; which not only plays an active role in ensuring the cavern stability and the construction safety, but also gets a certain experience for the similar project concerned.
