江西某水库采用水平定向钻法建造了一条坝下涵管,但运行仅几个月即发生垮塌.为深入探讨水平定向钻法在水库工程中应用的可行性,采用复核计算和层次分析的方式,分析了事故原因,结合水库工程的特点,从设计、施工、管理等方面总结了经验教训.主要结论是:将水平定向钻法应用于水利工程在理论上和技术上是可行的,但是不但要做到设计合理、指标明确、选材合适,还要把握钻进泥浆的配比、注浆压力的选取以及回填灌浆等关键技术,严格施工管理,这样才能保证工程安全运行.
江西某水庫採用水平定嚮鑽法建造瞭一條壩下涵管,但運行僅幾箇月即髮生垮塌.為深入探討水平定嚮鑽法在水庫工程中應用的可行性,採用複覈計算和層次分析的方式,分析瞭事故原因,結閤水庫工程的特點,從設計、施工、管理等方麵總結瞭經驗教訓.主要結論是:將水平定嚮鑽法應用于水利工程在理論上和技術上是可行的,但是不但要做到設計閤理、指標明確、選材閤適,還要把握鑽進泥漿的配比、註漿壓力的選取以及迴填灌漿等關鍵技術,嚴格施工管理,這樣纔能保證工程安全運行.

@@@@A new dam culvert was built using the horizontal directional drilling method in a reservoir of Jiangxi Provincebut it collapsed after a few months of operation .In order to explore the feasibility of the horizontal directional drilling method in the reservoir engineeringthe causes of the accident were analyzed using the recomputation and analytic hierarchy process .Moreover‐the characteristics of reservoir engineering were consideredwhich provided the lessons from the aspects of designconstructionand management .The results indicated that the horizontal directional drilling method is feasible theoretically and technically .How‐evera reasonable designa straightforward targetand an appropriate selection of material were required to ensure the safe opera‐tion of the project with the assurance of the key technologies such as the drilling mud ratiogrouting pressureand backfill grout‐ingand the strict construction management .
