Comparison and Selection Design of Seawall Type in Baishuitou Dike Section of Binhai New Area of Tianjin
The Binhai New Area of Tianjin is located on the west bank of Bohai Bay.The coastline starts from Jianhe estuary at the junction of Tianjin and Hebei Province in the north to the estuary of Canglang Canal in the south.Due to the flat topography of the coast,it has been hit by storm surges many times in history,causing varying degrees of economic damage.The current design standard of the moisture-proof seawall is moisture-proof standard 20~50 years combined with 7 wind.After many years of operation,most seawalls have uneven settlement,resulting in far from the moisture proof planning standard(moisture-proof standard 100~200 years combined with 50~100 years of wind waves).The construction of seawall upgrading needs to be carried out urgently.The comparison and selection,design and application of different types of seawall in Bai Shuitou dike section in Binhai New Area were mainly described in this paper.
