【摘要】 简要介绍了在昆明“湖畔之梦”工程中引进混凝土管桩所面临的问题。结合与预制方桩的比较 ,针对昆明 8度抗震设防及滇池湖畔饱和非均匀性软土地基薄壁管桩 (PTC)桩基抗震进行了专门验算。为解决地方标准 (如浙江、宁波标准 )对高烈度区限制管桩应用问题进行了探索与尝试 ,提出了相关设计建议。更多还原

【Abstract】 The superiority of reinforced spun concrete tubular pile and the problems are introduced, which appear in project“the dream of Hupan”in Kunming.Comparing with the precast concrete square pile, the aseismatic intensity checking computations is made for the featheredged concrete tubular pile applied in the heterogeneous soft foundation near the Dianchi Lake at the 8 degree seismic fortification intensity.The problems of the first application for the concrete tubular pile in some high intensity regions restricted by some local standards(such as Zhejiang standard)are tried to solve.更多还原
