伊朗TALEGHAN水利枢纽工程发电厂房位于库区左岸山体内，需要承受80 m深水头高度的渗透压力，对地下厂房的防渗要求极高，施工技术难度大。根据这一特点有针对性地对弱透水岩层采用了湿磨水泥进行灌注，取得了较好的灌浆效果。重点介绍了地下厂房四周封闭帷幕灌浆的施工方法，为类似工程的防渗灌浆施工提供了可借鉴的经验。
伊朗TALEGHAN水利樞紐工程髮電廠房位于庫區左岸山體內，需要承受80 m深水頭高度的滲透壓力，對地下廠房的防滲要求極高，施工技術難度大。根據這一特點有針對性地對弱透水巖層採用瞭濕磨水泥進行灌註，取得瞭較好的灌漿效果。重點介紹瞭地下廠房四週封閉帷幕灌漿的施工方法，為類似工程的防滲灌漿施工提供瞭可藉鑒的經驗。

Powerhouse of TALEGHAN water control project of Iran is located in the mountains on the left bank of reservoir area.With high seepage pressure of 80m water head height, the construction was difficult because of extremely high re-quirements for seepage control on underground powerhouse.On this basis, targeted wet grinding cement grouting was ap-plied in weak permeable layer with good effects.The paper mainly introduces the construction method of enclosed curtain grouting for underground powerhouse, which can be reference to the similar projects.
