摘　　要：基于卡萨格兰德法,分析并确定土体先期固结压力曲线的拟合数学模型,根据先期固结压力的数值计算原理,应用Matlab软件可实现其数值求解,实例表明,Matlab软件在土工试验数据处理上有很好的应用价值。Based on Casagrande method, using polynomial to fit pre-consolidation pressure curve and the fitted mathematical model of the curve is confirmed after analyzed and compared. According to use Matlab software, the numerical solutions of pre-consolidation pressure is successfully achieved based on the numerical method of the pre-consolidation pressure. Taking example to explain the Matlab software has much application values in dealing soil experiment data.
