菲律宾某电厂卸煤码头结构设计要点

Structural design points of coal unloading jetty for power plant in Philippines

随着我国“一带一路”倡议的实施,通常大型燃煤电厂都需要配备卸煤码头以满足厂区的煤炭运输。针对位于马尼拉湾口处的某卸煤码头结构设计问题,考虑工程区域台风季风浪条件恶劣、地震多发的自然特点,在保证结构安全和可靠性的前提下,结合中国和菲律宾当地规范对钢筋、混凝土和结构设计等方面的规定,确定适合本工程的码头结构形式、桩基形式和地震参数,并总结在台风频繁、地震多发的菲律宾进行码头设计的要点。结果表明,高桩梁板式码头结构对风浪有较好的适应性,二层系缆平台保证了船舶的安全靠泊,全直桩的灌注桩结构满足码头承重能力和结构抗震要求。

With the implementation of“the Belt and Road”initiative in China,large coal power plants usually need to be equipped with coal unloading jetty to satisfy the coal transportation in the plant area.For the structural design of a coal unloading jetty located at the mouth of Manila Bay,we consider the severe typhoon monsoon wave conditions and frequent earthquakes in the project area,combine the provisions of Chinese code and the local Philippine code on the design of steel rebar,concrete and structures into account under the premise of security and reliability of the structure,determine the jetty structure,pile foundation and seismic parameters suitable for the project,and summarize the key points of jetty design in the earthquake prone area like Philippines with frequent typhoons.The results show that the high-pile beam slab jetty structure has good adaptability to wind and waves.The second floor mooring platform ensures the safe berthing of the vessel.All vertical bored pile satisfies the load-bearing capacity and the seismic requirements of the structure.
