海港码头结构升级改造技术

结合海港码头结构升级改造的实际案例，对重力式和高桩码头的结构，划分为码头前沿线不变和码头前沿线前移两类。重力式码头在前沿线不变情况下，给出基床改造、基础前增加独立结构和以附属设施为主的综合改造3种案例；码头前沿线前移情况下给出新老结构结合式和新增独立结构2种案例。高桩码头前沿线不变情况下，给出分离式和结合式案例。

Upgrading and reforming methods of sea wharf structures

Based on the practical sea wharf structures upgrading and reforming cases,this paper classifies wharf structures into two categories depending on whether the wharf apron is advancing or not.In condition of fixing wharf apron,we present three practical reforming cases:reform of rubble bed,addition of independent structure ahead of foundation and addition of accessory structures.In condition of advancing wharf apron,two cases are presented:newly constructed structure combined with old structure or newly constructed structure independent to the old one.For the open type wharf on piles with fixed wharf apron,the cases of separated structure and combined structure are presented.
