摘　　要：沿海港口场地普遍存在深厚软土地基,在这种场地上建设大跨度钢结构厂房必须考虑地面堆载对建筑物桩基的负面影响,采用刚性地坪桩是其中的一种解决方案。利用有限元分析软件模拟堆载和地基,系统分析了配煤罩棚基础和刚性地坪桩基础的稳定性。结果表明:采用刚性地坪桩方案配煤罩棚的基础满足安全要求。Deep and soft soil foundations are common in coastal port sites. Therefore, the negative impact of ground surcharge loads on pile foundations of buildings must be considered while constructing workshops with large-span steel structures on such sites. The use of rigid floor piles is one of the solutions. In this paper, we simulate the surcharge loads and foundations by the finite element analysis software and systematically analyze the stability of the coal blending shed foundation and the rigid floor pile foundation. The result reveals that the coal blending shed with the rigid floor piles meets the safety requirements.
