摘　　要：通过正、负弯矩加载试验研究,揭示了新型高强钢筋混凝土预制弧板井壁螺栓式柔性接头力学特性,得到了确定接头抗弯刚度Kθ的试验参数,为今后科学设计该种新型冻结井壁结构提供了试验依据。The mechanical characteristic of the new flexible joints in the prefabricated arc board wall of a freezing well with high strength reinforced concrete（RC） is revealed through positive and negative moment loading tests. The parameters for determining the joint＇s flexural rigidity Kθ are obtained. This study is beneficial to the design of the new wall structure of freezing wells.
