地震会引起相邻结构发生碰撞，导致结构损伤甚至倒塌。为更准确研究结构的碰撞问题及影响，文中将精细积分算法用于结构碰撞的求解中，并进行了公式推导和算例验证。结果表明，精细积分法对于结构的碰撞问题是适用的，并有无条件稳定、精度高和受时间步长限制小的优点。

Adjacent structures will collide with each other when the earthquake occur,resulting in structural damage even collapse,therefore the research of the collision problem of the structure is very important.In order to more accurately research the collision problems of the structure and its influ-ence,in this paper,the precise integration algorithm is used to structure in the solution of the colli-sion,and formula deduction and numerical example verification.The results show that the precise in-tegration method for collision problem of the structure is applicable,and has the unconditional stabili-ty,high precision and restricted by time step of small advantages.
