Simulated High-Pile Dock Construction on the Impact of Coastal Erosion Based on Theoretical Models and Dou Theory - A Case of Suanshan Dock

Abstract

In order to investigate the renovation and expansion of coastal high-pile on the possible environmental impact of erosion and deposition, the changes of ocean current field and bottom erosion before and after the current field of renovation and expansion were simulated in use of an average two-dimensional vertical flow theoretical simulation model and Dou theory, based on ocean current Speed, flow and other measured data, integrated hydrological, meteorological and other historical information. The results showed that after the construction of Suanshan Dock , the increased siltation of Yang gong-shan Dock and Budui Dock code were approximately 1m and 0.5m respectively. Due to the high pile and bridge-type structure of high-pile dock , although the construction of Suanshan Dock would cause coastal area occurring a certain flow pattern changes , there were not significantly changes to the topography of basin . The underwater slope area would remain in a relatively stable state.
