摘要:
采用透水桩加速桩周土体固结,消除压桩施工过程中超静孔压的不利影响。利用ABAQUS有限元法对比静压桩和透水桩下桩周土体固结过程,发现相比静压桩,透水桩桩周0.1D范围内土体固结度达到90%时,耗时缩短1.55 d,土体固结速率提升了60.8%。结果表明:透水桩桩周土体固结速率较快,透水桩可以加速压桩施工过程中超静孔压的消散,消除其不利影响。
Abstract:
Permeable piles were used to accelerate soil consolidation and eliminate the adverse impact of excess pore pressure produced inpile driving process. Soil consolidation comparison between the permeable pile and the static pressure pile was made by ABAQUS finite element method. Compared with the static pressure pile, 1.55 d was saved and the consolidation rate was improved 60.8% when the degree of soil consolidation achieved 90% in the around of 0.1D range pile. Results showed that the soil consolidation rate around permeable pile was faster, permeable piles could be used to accelerate the excess pore pressure dissipation in pile driving process and eliminate the adverse impact of excess pore pressure.
