摘　　要：岩土体应力应变之间存在黄金分割比例—0.618和0.382这对数字关系,据此规律建立比较正确和简便的的定量计算—Can-Chen模式。此模式可用于确定桩的中和点和中性点,估算单桩实际承载力,估算地基土的竖向变形和侧向变形,估算建(构)筑物沉降量,深基坑围护设计和计算,确定深基坑支撑位置,预估超深沉井的卡位等。通过介绍其在岩土工程中的应用研究成果,以求岩土工程界试用、验证。Based on the comprehensive analysis and research on a lot of geotechnical engineering testing data obtained both at home and abroad >the authors have found that the numerical relationshop between 0. 618 and 0. 382--golden sectional proportion has been existed between stress and strain of the soil body and thus.more correct and simple quati-tive calculation--Gan-Chen Model has been set up just in light of this law. This model could be used to determine neutral point of the pile and also to estimate the real bearing capacity of the single pile.laterial and vertical deformation of foundation soil,the settlement of architectures and buildings and to design and calculate deep foundation pit bracing,to determine its suppo ting position and to estimate the fixed position of extra-deep well sunk etc.. By introducing the applied researching results which obtained in geotechnical engineering,the authors would like the model to be tested and e-valuated.
