地铁车站结构诱导缝应用研究现状与展望

摘要

地铁车站结构诱导缝可削弱车站结构的刚度，减少地铁车站结构在施工建设和后期运营中因混凝土结构的温度应力和不均匀沉降等引起其无序开裂。重点论述了诱导缝在地铁车站结构中的施工工艺、工作机理和诱导缝接缝的变形分析计算理论方法，并进一步分析了地铁车站结构诱导缝受力形式以及加强地铁车站结构诱导缝抗震性能研究的必要性。%Induced joint in subway station structure can weaken stiffness of the structure and reduce disordered cracking thereof resulting from the temperature stress of the concrete structure and the uneven settlement in the construction and post-operation. In view of this, the paper mainly explains its construction process, working mechanism, and theoretical methods for deformation analysis and calculation of such induced joints; moreover, the type of stress on the induced joints is further analyzed, and the application of the induced joints in subway station structures for the necessity of earthquake resistance is studied.
