浙东沿海地区沉桩引起的孔隙水压力的计算

沿海软土地区中桩基设计与沉桩引起的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，并对实测资料进行了对比和概括，探讨了沉桩时单桩与群桩周围土中产生的孔隙水压力的大小、分布及影响范围，对具体工程桩的施工和设计均有参考意义。

Calculation on the Pore Water Pressure Caused by Pile Sinking in the Coastal Area of East Zhejiang Province

The design of pile foundation in soft soil area of coastal areas is closely related with the pore water pressure and its dissipation. Through the theoretical study and information analysis on the process of sinking of extrusion pile and the trade-off study and summary of the measure data, the pore water pressure, pressure distribution and effective extent in the surrounding soil of single pile and group of piles during the sinking of pile are discussed, which provides a satisfactory reference to the construction and design of engineering piling.
