外水壓力外水壓力external water pressure wai弓}:ui yali外水壓力(external water pressure)作用在地下結構或建筑物外壁的水壓力。外水壓力是水工隧洞或其它地下建筑物的基本荷載之一。對有壓隧洞，它對內水壓力有抵消作用，但在檢修期則成為主要荷載;對無壓隧洞，可采取引沐方法減小外水壓力。 外水壓力的大小與洞外水的埋藏、補給及排水條件、隔水層的位置、周圍巖石節理裂隙的分布情況、襯砌本身和周圍巖石的透水性能，以及二者的結合情況有關。對較長的隧洞和地下管道，地下水位沿程變化較大，工程地質及水文地質條件復雜，沿線的巖體與建筑物外壁又有一定的嵌固作用，故確切地計算外水壓力的數值比較困難。常用的方法是:先根據水文地質條件和工程布置，并考慮水庫投入運行后可能引起的地下水位變化等因素，分析確定地下水位線，再將地下水位線以下的水柱高乘以折減系數準，作為估算襯砌外緣的外水壓力值。 方值的確定，要結合當地的工程地質、水文地質及防滲、排水等情況，并輔以必要的觀測資料，進行全面分析確定。初定時，也可根據工程類比，參照地下水活動情況以及可能采取的工程措施，按最不利的情況選取。當地下水活動很微弱，洞壁有滲水或滴水時，口取為O一0.4;隨著地下水活動的加劇，洞內嚴重流水時，刀值可高達0.65一1.0。當圍巖采取防滲、排水措施時，方值可適當降低，但如在確定地下水位時，已經考慮了這個因素，則不宜再降低。當有內水荷載組合時，口值取小值。 實際上，襯砌與圍巖可視為一個整體，水荷載是以滲流體積力的方式作用于地下水位線以下的整個巖體，滲流體積力按內外水所形成的滲流場決定。故外水壓力是場力而不是邊界力。根據這一概念計算隧洞襯砌的應力較為合理，這是目前發展的趨勢。 (楊文祥)
