适用范围：This European Standard establishes general principles for the execution of diaphragm walls as either retainingwalls or cut-off walls.NOTE 1 This standard covers only structures constructed in a trench excavated with a support fluid or in dry conditions,where soil is removed and replaced by concrete or slurry and with wall thickness B ≥ 40 cm.NOTE 2 Diaphragm walls can be permanent or temporary structures.NOTE 3 The following types of structure are considered:a) retaining walls: usually constructed to support the sides of an excavation in the ground. They include:1) cast in situ concrete diaphragm walls;2) precast concrete diaphragm walls;3) reinforced slurry walls;b) cut-off walls: usually constructed to prevent migration of groundwater, clear or polluted, or of other contaminantspresent in the ground. They include:1) slurry walls (possibly with membranes or sheet piles);2) plastic concrete walls.NOTE 4 Walls formed shallow vertical trenches (typically excavations with a ratio of depth over thickness D/B < 5 orD < 5 m) are not covered by this standard.
