摘要

提出了一种预测单桩和墩破坏时荷载沉降特性的简便方法。该方法以桩身沉降特性的理论弹性分析结果为基础,假定基础荷载与沉降之间的破坏呈线性关系。对已发表的粘土和砂土中桩的荷载试验进行了分析,并提出了土模量的经验值。实测荷载沉降行为与预测荷载沉降行为的比较显示出合理的一致性。

LOAD-SETTLEMENT PREDICTION FOR PILES AND PIERS
A simple method is presented for the prediction of load-settlement behavior to failure of single piles and piers. The results of theoretical elastic analysis of pile settlement behavior are used as a basis for the method, which assumes linear relationships to failure between base load and settlement. An analysis is made of several published and load tests on piles in clay and sand and empirical values of soil modulus are suggested. Comparisons between observed and predicted load-settlement behavior show reasonable agreement.
