该文经过两个场地的对比试验实例,阐明了夯扩桩的特性和桩承载力的可塑性。在桩持力层恒定,桩径、桩长、桩距相同条件下,夯扩桩可利用夯扩工艺、夯扩参数的有效调整,大幅度提高桩的承载力,充分挖掘持力层的桩端承载潜力,以适应建筑物对地基基础的承载需求。
This article passes the comparative experiment example of two sites, expounds the characteristics of the rammed-expanded pile and the plasticity of the pile bearing capacity. Under the same conditions of constant pile-holding force, pile diameter, pile length and pile spacing, the rammed-expanded pile can make use of ramming expansion process and effective adjustment of ramming expansion parameters to greatly improve the bearing capacity of the pile and fully excavate the pile End bearing potential to accommodate the building’s foundation bearing capacity needs.
