Abstract:	連續壁作為地下擋土水壁已有50年以上施工歷史，基本概念為利用器械於欲執行擋土水處挖掘適當深度之深槽，挖掘中以穩定液換置土塊，穩定液膜於槽壁上形成，作用類似模板，穩定液之靜壓則作為槽壁穩定之支撐，依使用器械設備及擋土水壁之需求外形及槽壁垂直面接合型態予以適當劃分長度，定名為單元(Panel of Element)，施工時依單元尺寸製作準確之鋼筋籠吊放入槽溝，再以特密管澆置混凝土，目前連續壁工法已成為當前深開挖工程擋土結構之主流，然而如何確認在地質條件不佳之環境下，完成之連續壁是否完整，其之檢測作業在工程實務 The construction of diaphragm walls to be applied as groundwater barriers and retaining walls has been in use for more than 50 years. Basically it requires an appropriate trench being kept in engineered fluid to form a slurry. The slurry exerts hydraulic
