（蘇州設(shè)計(jì)研究院股份有限公司， 蘇州 215021）［摘要］針對蘇州軌道交通2號線太平車輛段上蓋物業(yè)開發(fā)項(xiàng)目鉆孔灌注樁工程，采用堆載法和自平衡法進(jìn)行抗壓承載力靜載試驗(yàn)。概述了本次試驗(yàn)情況，整理了試驗(yàn)數(shù)據(jù)，并將堆載法與自平衡法試驗(yàn)數(shù)據(jù)進(jìn)行了對比分析，得出了本工程中自平衡法修正系數(shù)K的取值。分析結(jié)果表明：兩種試驗(yàn)方法均取得了較好的效果，自平衡法表現(xiàn)出一定的優(yōu)越性。［關(guān)鍵詞］鉆孔灌注樁； 堆載法； 自平衡法； Q-s曲線； 修正系數(shù)中圖分類號：TU473.1+6 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2013)20-0096-04Comparative analysis on compressive bearing capacity test methods of the drilled grouting pileXu Wenxi, Zhang Min, Zhu Yi, Wu Wenchun, Yang Yukun(Suzhou Institute of Architectural Design Co., Ltd., Suzhou 215021, China)Abstract: The drilled grouting pile engineering of Taipingcheliang project on Suzhou metro line two has been tested using the traditional piling-up weights method and the self-balanced method to carried out the compressive bearing capacity test. Tests were overviewed as well as the data to compare two different methods. Correction factor K of self-balanced method in this project was achieved. Results indicate that both of two test methods are effective while self-balanced method is better.Keywords: drilled grouting pile; traditional piling-up weights method; self-balanced method; Q-s curve; correction factor作者簡介：徐文希，高級工程師，一級注冊結(jié)構(gòu)工程師，Email：wenxi.xu@siad-c.com。參考文獻(xiàn)［1］DGJ 32/TJ 77—2009 基樁自平衡法靜載試驗(yàn)技術(shù)規(guī)［S］．南京：江蘇科學(xué)技術(shù)出版社，2009．［2］魯良輝.樁承載力自平衡測試轉(zhuǎn)換方法研究［D］．南京：東南大學(xué)，2004．［3］戴國亮.樁承載力自平衡測試法的理論與實(shí)踐［D］．南京：東南大學(xué)，2003．
