环形槽应力释放法中应力零点槽深数值计算

Numerical compute of the slot depth with zero stress in ring-slot stress-releasing method

在预应力混凝土现存预应力的研究方面提出了环形槽应力释放法,对两根预应力混凝土梁进行了分析,解决了应力释放法中最重要的最佳槽深问题,并探讨应力零点槽深的影响因素,对实际工程具有一定的指导意义。

Give the method of stress-releasing with ring-slot in the study of existing prestressing force in the prestressed concrete, and analyse two prestressed concrete beams, and solve the importance problem of the the best depth with which the stress is released to zero, and discuss the influence factors of the slot depth, has guide significance of practice project.
