摘　　要：本文在考虑地基沉降的基础上建立土方量计算模型,把土方量的计算分为两个构成要素,并结合现场沉降观测结果进行分析计算,从而计算出由于地基沉降而引起土方量的增加量,最终推导出堆载量的一个计算公式。In this paper, a calculation model for the filling volume on the soft ground with pre - loading was established based in consideration of foundation settlement. Calculation method of the earthwork volume was divided into two elements, and it has been analyzed with the observed results of foundation settlement. So the increased amount of earthwork caused by foundation settlement was accurately calculated. Ultimately the accurate calculation formula was deduced.
