| 摘 要： | 土的结构性对土的工程力学性质影响较大。邓肯-张模型是基于重塑土而建立的模型,荷载较大时,偏差较大。文中通过三轴试验,对考虑结构性邓肯-张模型在吹填软土中的应用进行了试验研究。结果表明：考虑结构性邓肯-张模型比原始邓肯-张模型更适合有结构性的吹填软土。该研究成果对吹填场地沉降计算及控制具有一定的理论价值。

| Abstract: | Soil structure has great influence on engineering mechanic properties of soil.Duncan-Chang model is based on the reconstituted clays,when load is heavy,the deflection is become large.Through triaxial test to study on Duncan-Chang model applied in dredger fill considering structural characteristics.The results showed that Duncan-Chang model is more suitable for soft structural dredger fill than the original Duncan-Chang model.The research has certain theoretical value to settlement calculation and control of... |
