摘要：

本文针对下卧基岩埋深较浅的复杂地质情况,提出了嵌岩灌注桩方案、钢管桩及钢筋砼大管桩嵌岩方案、H型钢与钢筋砼方桩的复合桩方案及深层水泥搅拌法方案,利用合理的码头结构平面布置形式来适应靠船需要的方案等建港对策,并从设计基本思路、方案适用范围、设计及施工中应引起注意的问题等3个方面对上述建港对策进行了详细的阐述。

In view of the complex geological formations with the underlying rock bed embedded rather shallowly,the authors proposed a number of countermeasures to meet the requirements of safe berthing at the quays and wharves with a plan layout of rational quay structures,which include the rocksocketed castinsitu piles,circular steel piles and rocksocketed large diameter reinforced concrete piles,composite piles of Hsteel with reinforced concrete square piles,and cement deep mixingThe authors further expound on the three aspects of the basic principles of the designs,scope of application of the countermeasures,and problems that should be taken into consideration during the design and construction period
