摘要
饱和软土地基中桩基设计与沉桩引起的超孔隙水压力大小及其消散有密切关系。通过对挤土桩沉桩过程的理论研究和资料分析,探讨了沉桩时单桩与群桩周围土中产生的超孔隙水压力的大小、分布及影响范围。并对实测资料进行了对比和概述。
The dissipation of excess pore water pressure has a direct bearing on the design of pile foundation in saturated soft soil. By theoretical analyses and practical measurement during pile driving,the magnitude, distribution and the range of the excess pore water pressure caused by an installing piles and pile group in soil around the piles are discussed. The comparisons and summarizations of the measured data are also carried out.
