摘　　要：盐田东码头护岸建设安全等级高、设计荷载大。针对其下卧不良地质软弱土层埋藏深、厚度大,分布广的问题,进行软基处理方案研究,从而确定合适的软基处理方法,提高护岸整体稳定安全系数。提出开挖换填、水泥搅拌桩、碎石桩及轻质土4种软基处理方案,计算结果表明,采用4种软基处理方案后,护岸整体稳定安全系数均可满足要求。从造价、施工便利性、可靠性、工期等方面进行综合比选,并参考建设需求,最终采用开挖换填方案进行地基处理,该方案具有施工简便、工艺成熟、易于控制的优点。The safety level of the wharf revetment construction in eastern Yantian Port is high and the design load is large.In view of the problems of deep burial,large thickness and wide distribution of the poor geological soft soil layer beneath the revetment,the soft foundation treatment scheme is studied,so as to determine the appropriate soft foundation treatment method and improve the overall stability and safety factor of the revetment.Four soft foundation treatment schemes are proposed,including excavation and replacement scheme,cement mixing pile scheme,gravel pile scheme,and lightweight soil scheme.The calculation results show that the overall stability and safety factor of the revetment can meet the requirements after adopting the four soft foundation treatment schemes.After comprehensive comparison from the aspects of cost,construction convenience,reliability and construction period,and referring to the construction requirements,the excavation and replacement scheme is adopted for weak soil treatment.The advantages of the recommended scheme are superior safety,convenient construction,mature technology,and easy quality control.
