靜壓樁施工對周圍環境影響的分析方法,主要有小孔擴張理論和數值模拟的方法。
An appropriate finite element model was given according to the actual process of jacked pile. This model adopted the rational constitutive model of soil and finite deformation theory.
采用合適的土體屈服準則及有限變形理論,通過在樁—土界面設置接觸以及在樁頂施加位移荷載建立了符合壓樁實際的有限元模型。
在建築工程領域,"jacked pile"(頂進樁/靜壓樁)是一種通過液壓頂進設備将預制樁體垂直壓入地層的深基礎施工技術。該技術通過反力裝置将液壓産生的巨大壓力傳導至樁體,使樁體克服土壤阻力逐漸貫入持力層。
根據美國土木工程師學會(ASCE)的施工标準,頂進樁施工流程包含三個核心環節:
相較于傳統打樁工藝,頂進樁具有以下技術優勢:
該技術已成功應用于上海中心大廈樁基工程,項目采用直徑600mm的PHC管樁,單樁承載力特征值達3800kN(上海岩土工程勘察設計研究院技術報告)。對于施工質量控制,建議參考《靜壓樁施工技術規程》(CECS 235)中的垂直度偏差控制指标(≤0.5%樁長)。
“jacked pile”是土木工程領域的專業術語,指通過靜力壓入法施工的樁基,其核心含義和特點如下:
如需進一步了解施工參數或案例,可參考工程規範或專業文獻。
