摘要
介绍了预应力混凝土先简支后连续梁 1∶5的模型设计、试验方法。根据弹性试验、开裂试验结果 ,研究分析该类结构的工艺特点。
The paper concisely introduces the design on a scale of 1∶5 and test method of the railway prestressed concrete model beam constructed by simple and continuous support. Based on the test results about elasticity crack of model beam, the characteristic of technology the anticrack property especially in the wet joint section and the regularity of crack growth are analyzed.
