In view of the natural conditions in loess area of gansu, in the light of investigation conditions of seepage of built loess and weak rock highway tunnels in this area and classification of water gushing conditions for railway tunnels, and by engineering analogism, the classification of tunnel water gushing types suited the structure design of highway tunnel waterproof and drainage, and the three methods for checking and subdividing water gushing types are presented

    摘要針對甘肅黃土區的自然條件，依據該地區已建黃土及軟巖公路隧道滲漏水調查情況和鐵路隨道涌水狀態分類，運用工程類比法提出適合該地區公路隧道防排水結構設計的隧道涌水類型劃分及對涌水類型校核與細分的三種方法。
  2. The method of close water test has been used for a long time, so richer experience has been achieved. however, it not only takes pains and time, but also consumes raw materials during the close water test because of miscellaneous working procedures such as bricklaying in the two ends of pipe, water - repellent layer plastering, maintaining and water offletting, brick - block backouting after the test, especially in the region short of water and some drainage pipe with prop - pipe construction. in order to satisfy the fast development of municipal construction, new detection methods should be developed

    閉水試驗方法因其應用時間較長，目前已積累了較豐富的經驗，但在閉水試驗時，管道兩端砌築磚堵、抹防水層、養護、灌水浸泡，以及試驗后的放水、磚堵拆除等繁雜工序，不僅費工、費時，而且消耗原材料，尤其是在缺水的地區以及頂管施工的無壓管道，這些矛盾更加突出；因此，為滿足迅速發展的市政建設需要，有必要探索新的檢測方法，閉氣試驗就是其中一種，但是閉氣試驗目前還不完善，有待于進一步深入研究。
