将整体现浇式预应力锚索桩板墙运用在混凝土连续浇筑施工中,虽然可以缩短工期,减少成本投入,但其设计计算方法还不成熟.通过对云南某山区高速公路上整体现浇预应力锚索桩板墙结构形式实体工程系统的型试验研究,实测锚索桩板墙在不同工况下的内力及填土土压力,以此为基础分析了该支挡结构在各工况下的力学特征,为设计计算方法的改进提供参考据.本文选取工后工况下桩板墙的力学特征分析进行阐述.
將整體現澆式預應力錨索樁闆牆運用在混凝土連續澆築施工中,雖然可以縮短工期,減少成本投入,但其設計計算方法還不成熟.通過對雲南某山區高速公路上整體現澆預應力錨索樁闆牆結構形式實體工程繫統的型試驗研究,實測錨索樁闆牆在不同工況下的內力及填土土壓力,以此為基礎分析瞭該支擋結構在各工況下的力學特徵,為設計計算方法的改進提供參攷據.本文選取工後工況下樁闆牆的力學特徵分析進行闡述.

Integral cast-type prestressed anchor cable sheet pile wall used in the construction of continuous cast concrete shortens the duration and reduces capital costs, but its design calculation method is not yet ripe. By the research on prototype test of whole in-situ prestressed anchor cable sheet pile wall structure entities of a mountain highway in Yunnan province, measures the internal force and fill stress of anchor cable sheet pile wall in different conditions, based on this, analyzes the mechanical characteristics of retaining structures in all of the following conditions, providing reference for improvement of design calculation method. The paper presents the mechanical characteristics of pile-sheet retaining wall under elaboration.
