钢管桩能承受较大的锤击力,而且在工地焊接接头的可靠性较高,因此能充分打入较深的承载层。在软土地基,下沉开口的钢管桩,还可以大大减少对地基土的挤压,有利于减少对邻近建筑物和地下构筑物的影响。所以在工程中的应用越来越广泛。现就钢管桩在上海软土地基中施工的一般顺序及相应 Steel pipe piles can withstand large hammering forces, and the reliability of welded joints at the construction site is high, so that deeper load-bearing layers can be fully penetrated. In soft soil foundations, steel pipe piles that sink and open can also greatly reduce the compression of the foundation soil, which will help reduce the impact on neighboring buildings and underground structures. So more and more widely used in the project. The general sequence of construction of steel pipe piles in Shanghai soft soils and their corresponding
