[提要] 通過對復(fù)合地基中剛性樁與柔性樁不同的破壞機(jī)制和承載特陛、影響復(fù)合地基強(qiáng)度和剛度的主要因素：有效樁長、置換率、樁土應(yīng)力比和樁土變形協(xié)調(diào)等分析比較，探討剛性樁復(fù)合地基用于一般十～二十層高層建筑的軟土地基處理的實(shí)用性和經(jīng)濟(jì)性。根據(jù)數(shù)項工程實(shí)例和靜載試驗結(jié)果說明加固效果，并簡單介紹剛性樁成樁工藝。
[關(guān)鍵詞] 剛性樁 柔性樁 復(fù)合地基 變形協(xié)調(diào) 承載力This paper compares and analyses coordinately different failure mechanism and bearing capacity characteristics of composite foundation with rigid and flexible pile respectively, and factors which influence strength and rigidity of composite foundation, including the effective of pile length, replacement rate, stress ratio and deformation of pile soil, it discusses the practicability and economy of adopting rigid pile composite foundation on high-nse building (10 - 20 storeys high) built on soft foundation. According to the graphics of some static loading tests, it explains the strengthening effects of the rigid pile composite foundation and briefly iritroduces piling technology of rigid pile.
Keywords: rigid pile; flexible pile; composite foundation; deformed coordination; bearing capacity
