The improved deep plate loading test device was introduced. By means of artificial digging hole, the device formed an effective counterforce system using reactions from geotechnical layer above the working face. The test data were collected and analyzed to get characteristic values of foundation bearing capacity at three points, and finally the characteristic value of foundation bearing capacity of 4 500kPa and deformation modulus of 178.45MPa were determined.Keywords: deep plate loading test; load-settlement curve; bearing capacity of foundation; deformation modulus作者簡介：武丹丹，碩士研究生，Email：15155911262@163.com。參考文獻［1］GB 50021—2001巖土工程勘察規(guī)范［S］. 2009年版.北京：中國建筑工業(yè)出版社，2009.［2］GB 50007—2011 建筑地基基礎(chǔ)設(shè)計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2012.［3］楊國春, 吳銀柱, 于波. 高層建筑深層平板載荷試驗的研究［J］.地質(zhì)與勘探, 2002，38 (4)：90-93.［4］張力群. 深層平板載荷試驗的實踐［J］. 西部探礦工程, 2005，17 (S1)：15-16.［5］王凌寒, 程澤海, 祝江鴻. 深層平板載荷試驗確定樁端土承載力和變形模量［J］. 建筑科學(xué), 2010，26 (5)：14-16.
