Application of Sheet Pile Wall in a Channel to Upgrade Waterways

With upgrading Hangzhou-Shanghai Waterway of Beijing-Hangzhou Grand Canal as the background, it is difficult and highly costly to upgrade waterways with traditional shoring methods according to the shortage of land for the Yangtze River Delta region. The feasibility of concrete sheet pile as vertical shoring is studied by finite difference analysis method. Earth pressure, settlement, horizontal displacement of shoring structure and the pile's stress and strain variation are obtained by simulating the design conditions and checking conditions before and after dredging of river channel. A comparative analysis is carried out between field test results and the simulations, which indicates that the medium-or-short thin concrete sheet-pile structure can be used as the shoring structure to upgrade waterways without increasing the width of water surface for its anti-overturning and sliding characters.
