摘　　要：在马六甲海峡高烈度环境的滨海深厚软弱地基条件下,存在地基工程力学性质、桩基持力层以及桩体的轴向承载力和横向荷载反应等诸多地基与基础设计问题。本文在软弱地基的工程力学性质分析研究基础上,通过桩体轴向承载力及横向荷载反应分析,确定桩端持力层的地基层位,获得该地基条件下不同规格钢管桩和混凝土管桩,在桩顶固定情况下的容许弯矩、容许弯矩产生的横向荷载以及横向荷载引起的桩顶移位等分析计算成果。为该特定的深厚软弱地基条件下的基础设计,提供可靠的技术依据。On the conditions of deep and coast-soft ground in high intensity environment on the Malacca Straits,it exists the ground and foundation design problems on the mechanical properties of foundation works,pile bearing stratum,the axial bearing capacity of pile and lateral load response,and so on.In this paper,it based on the analysis and study of mechanical properties of soft ground,and through the pile axial bearing capacity and analysis on the lateral load response which have to determined the horizon of ground of the pile tip bearing stratum.And then it have obtained analysis and calculation results on different specifications of steel pipe pile and concrete pile on this ground condition,and allowable bending moment and lateral loads produced by allowable bending moment and pile displacement produced by lateral loads in the case of fixed head pile.In order to provide reliable technical basis for foundation design in this specific deep and soft ground condition.
