摘　　要：通过模型试验研究 ,确定了独柱式四桩承台的破坏模式和力学计算模型 ,在分析试验结果的基础上 ,提出了改善承台混凝土抗裂性能的技术措施及方法 .研究结果对城市桥梁现行的独柱式四桩承台设计方法的改进具有一定的指导意义 .The damage model and mechanical calculations were validated by this study. Based on the analysis of the test results technical methods to improve the properties were developed to prevent cracking of reinforced concrete in the pile foundation. The test results provided us with guidelines for proper design of single columns supported by four pile cap used in bridge construction.
