中文摘要:
      在目前用海政策下,码头采用透水结构更为可行。结合工程实例,综合考虑自然条件及使用要求,针对常规透空沉箱墩在低高程、大荷载、浅基岩情况下存在的问题,通过理论计算及物理模型试验,对结构进行受力分析对比,并从方便施工角度进行优化,提出装配式沉箱墩码头结构。新结构能够满足码头面低的使用要求,承受较大使用荷载和波浪力,提高了对基础不均匀沉降的适应性,为在地质条件不适宜采用桩基结构的地区建设透空码头结构,提供了经济性更好、施工便利性更强的结构选型。装配式沉箱墩码头结构已在日照岚山港区得到应用,可为类似条件下建设透水码头结构提供借鉴。
英文摘要:
      Under the current policy of sea area use,application of permeable wharf is more viable.This paper combines engineering example,comprehensively considers natural conditions and usage requirements,and addresses problems of conventional pier wharf under low elevation,heavy load and shallow batholith conditions.Through theoretical calculation and physical model tests,the structure is analyzed and compared for stress,and optimized from the perspective of convenient construction.A prefabricated caisson pier wharf structure is proposed.The new structure can meet the requirements of low elevation of wharf surface,resist considerable service loads and wave force,improve the adaptability to uneven settlement of the foundation,and provide a more economical and convenient structural selection for the construction of permeable wharf structures in areas where geological conditions are not suitable for using pile foundation structures.The prefabricated caisson pier wharf has been applied in the Lanshan Port area of Rizhao,which provides reference for the construction of permeable wharf under similar conditions.
