摘　　要：通过建立完善的力学模型,分析保证斜拉桥安全坍塌时应控制的关键构件的运动轨迹。据此提出完成这一设计思想应采取深孔爆破、水压爆破及浅眼爆破相结合的最佳方案。同时,采用计算机动态仿真技术对大桥的爆破过程进行全时段的爆破坍塌仿真,以此来检验完善系统设计的可靠性和安全性。A mechanical model is established to study the motion locus of key structures that must be controlled carefully for blasting the cable-stayed bridge safely.On these grounds,it is confirmed that the general blasting scheme of combining the long-hole and short-hole blasting with water-pressure blasting should be adopted so as to realize the design idea.At the same time,the dynamic simulation technology is used to simulate the collapsing procedure of the bridge blasted,examining the reliability of blasting design.
