spot at joint of adjacent structures; (5) It shall be compatible with the neighbouring buildings and environment; (6) It shall be prone to repair and reinforce. 3.0.2 Where the revetment is composed of several straight segments, then these segments shall be connected by circular arc or broken line. 3.0.3 The revetment engineering shall be divided into segments according to the variance in such conditions as water depth, wave, geology and landform, and shall adopt different cross sectional dimensions or different structural types. 3.0.4 The structural type of revetment shall be determined through technical and economical comparison according to such factors as natural conditions, material source, service requirements and construction conditions. 3.0.5 The revetment structure may adopt slope type revetment, vertical revetment or the slope type and vertical combined structural type. The slope type revetment should be adopted in such district with low revetment slope, small water depth, poor base, rich stone source and sufficient land as well as the revetment slope adopting on site sloping; and the vertical revetment should be adopted in such district with steep revetment slope, large water depth, good base, small depth of bank line and insufficient land. 3.0.6 As for the slope type and vertical combined revetment structure, if the height of straight wall is small and the mainly the rubble filled slope is adopted, the revetment engineering may be designed according to the slope type revetment with breast wall; if the height of straight wall is large, the revetment engineering may be designed according to the vertical revetment on rubble bedding foundation. 3.0.7 The design of revetment engineering shall take the following three kinds of design conditions into consideration: (1) Persistent condition: the revetment engineering during the usage period of structure shall be designed respectively according to the limit state of bearing capacity and the serviceability limit state; (2) Transient condition: generally, the construction period and the usage period with a certain kind of special short term load shall be designed only according to the limit state of bearing capacity, and if necessary, may also be designed according to serviceability limit state; (3) Accidental condition: the usage period shall be designed only according to the limit state of bearing capacity when suffering from such Accidental actions as seismic action.
