Some new innovative constructions and technologies for improvement of port structures are worked out and discussed. The aims of innovations are to increase structures' reliability, to decrease cost of construction and maintenance, to simplify technology and cost of building. For these purposes either some main bearing elements or structures in whole are modified or improved. In particular different improved waterfront constructions as well as retaining walls and coastal protection (gravity, piled, sheet piling, etc.) for use in various soil conditions are outlined. One of them incorporates trapezoidal blocks forming columns, each block in the column contacts the others either with smaller or larger bases. Another design incorporates blocks that are constructed with holes ran through the centres of gravity of the blocks. Rigid cylinder element running through the holes of several adjacent blocks allows them to be joined forming large size units, The structure consisting of wedge form retaining wall is original but simple to construct, Some new designs based on perfection of sheet-piling walls (sheet piles with curvilinear cross-section having a form of semi-rings) are proposed for different applications. Proposals on modernization of some traditional structures and technologies are discussed. 展开更多
