采用三维连续介质快速拉格朗日法（FLAC3D ）对实际工程中灌注桩在沉渣影响下的竖向承载特性及沉降特性进行了数值模拟分析，并与静载荷竖向承载特性试验实测结果（Q - S 曲线）进行了对比，两者互相补充和相互验证。进而分别研究了沉渣厚度和沉渣性质对桩体极限承载力和沉降的影响，结果表明：沉渣厚度和沉渣性质对桩承载力的折减，分别存在一个影响曲线，为实际单桩承载力的计算提供依据。

Using the method of Fast Lagrange Analysis of Continua in 3 Dimensions (FLAC3D ) ,the vertical bearing ca-pacity and settlement characteristics of the bored pile influenced by the sediment in practical engineerings are analyzed in numerical simulation ,and compared with the static load test results of the vertical load-bearing characteristics (Q - S curve) ,then the two results are completed and authenticated each other .Simultaneously ,the effects of the sediment thickness and sediment properties on the pile’s ultimate bearing capacity and settlement are studied respectively .The re-sults show that the reduction of the sediment thickness and sediment properties on the pile ’s bearing capacity has a curve respectively ,which could provide bases for the calculation of the actual bearing capacity of single pile .
