海岸海床地基土孔隙水压力的拟合模式研究

Study on Pore Water Pressure Development of Seabed Subsoil

针对土体在振动作用下产生孔隙水压力将直接危及建筑物及其地基的安全稳定,基于我国东部沿海地区砂土、粉土、残积土等海岸海床地基土的动三轴试验资料,研究了不同类型地基土的孔压拟合公式及其特性,研究结果可供实际工程参考。

Under the action of vibration effect,soil mass produces pore water pressure,which directly endangers the safety of building and its foundation.Based on the seabed subsoil data of dynamic tri-axial test including sand soil,silt and residual soil in eastern coastal China,this paper studies the pore pressure fitting formula and characteristics of different foundation soils.The results can provide reference for engineering application.
