摘要
依据理论研究、模型试验和工程实测成果 ,对扩展基础基底压力的非线性分布进行研究 ;从扩展基础冲切破坏的实际性状出发 ,在定性分析基底压力非线性分布对扩展基础抗冲切承载力不利影响的基础上 ,采用简化的计算方法进行定量估算 ,估算值与 Press模型试验实测值很接近 。
Based on the achievements in theoretical study,model and engineering test,non linear distribution of stress beneath a spread foundation is researched.Depended on the failure character of cone penetration,and a available simplified estimating method is introduced,then,the disadvantageous effect on the code formula of cone penetration resistance of a spread foundation influenced by nonlinear distribution of stress is estimated quantitatively.At last the properly usage for the code formula in design are recommended.
