[提要] 針對樁基場地試樁樣本數(shù)偏少的狀況，采用靜力觸探參數(shù)估算單樁極限承載力，并用估算值參與試
樁統(tǒng)計分析，評價樁基場地。結(jié)合工程實例介紹了評價方法，供探討。
[關(guān)鍵詞] 靜力觸探靜壓樁承載力 可靠性評價In view of existing situation that the test pile samples of pile foundation are less than expected, the parameters of the static cone penetrations tests are adopted to estimate the bearing capacity of single pile. Then we make testing statistics analysis by using this value and evaluate the pile foundation site. An evaluation method considering an engineering case is introduced.
