湖相沉积土层中等直径劲性复合桩的承载力计算与分析

摘要

We calculated and analyzed the bearing capacity of strength composite piles which located in the lacustrine sedimentation with five methods used by engineers. The result showed that cement-soil have major impact on the bearing capacity of strength composite piles. We found cement-soil share of the bearing capacity of strength composite piles with the same diameter in the lacustrine sedimentation, and found that factor of the side resistance of pile have major impact on the bearing capacity of strength composite piles. We will get the practical and safe results while considering the various factors on the influence of the bearing capacity of strength composite piles, and achieve economic and environmental benefit.%本文采用目前五个具有代表性规范对湖相沉积土层中劲性复合桩桩身承载力进行计算复核与分析,得出了在采用与芯桩等直径原位注浆搅拌情况下,土体经注浆搅拌后对桩身承载力依然具有较大的影响的结论.给出了在特定工程条件下注浆搅拌对桩身承载力的贡献值.劲性复合桩侧阻力调整系数对桩身承载力有较大的影响,工程中需结合地区经验综合考虑,才能得出符合实际、安全的计算结果,为工程带来合理的经济环境效益.
