【摘要】 由于桩端后注浆灌注桩可弥补常规灌注桩自身的不足,因而桩端后注浆灌注桩在上海软土地区逐步得到广泛的工程应用,但目前在上海地区对桩端后注浆灌注桩单桩极限承载力的估算尚无合适的计算方法。本文根据上海地区十余个比较典型的桩端后注浆灌注桩桩基工程实例,提出了上海地区的桩端后注浆桩单桩极限承载力的估算方法——灌注桩经验参数上限法。更多还原

【Abstract】 Because of the shortcomings of bored piles in Shanghai soft soil area,base-grouting bored piles have been widely used in the foundation engineering of buildings,but there is not a suitable calculation method of the ultimate bearing capacity of a single base-grouting bored pile in Shanghai soft soil area.Based on the experience of tens of pile foundations in which base-grouting bored piles are used,a new upper boundary method of empirical parameter has been put forward to estimate the ultimate bearing capacity of a single base-grouting bored pile.更多还原
