摘要
合适的管桩静压施工的终压力条件是保证桩基所需的竖向极限承载力的关键,通过管桩自身的承载能力及具有多点式夹桩机构的桩机抱压施工时对桩所产生的作用力分析,结合聊城地区几例预应力高强混凝土管桩静压施工的终压力值与静荷载试桩结果,讨论终压力满足单桩竖向极限承载力的条件,获得了在粉土粘土做持力层条件下的终压力与单桩竖向极限承载力之间的关系系数。
On the base of the construction final pressure of and several static load test results in Liaocheng district,analyzing concrete pipe pile in the process of construction,and researching struction Pressure Of Static-press Pile and the ultimate vertical prestressed high strength concrete piles pile the final pressure standard of static prssure on the relationship between the Final conbearing capacity of a single pile, the final pressure effect factor between them have calculated driving piles into silt and claypan as supporting layer.
