4辆运送瓷土的大货车有3辆是江西车牌，1辆是河源车牌

序号	月／日	地点	工程	原因	死／伤
1	6/19	广东河源	粤赣高速匝道桥	疑似独柱墩	1/4

［附录1］

该桥急需改造，车辆不会遵照设计规范行驶，设计规范只是

统计成果，不能适用于特殊情况的个别人，而且也不能约束违规者，

那是管理的职责。如果管理不能面面俱到，就要改善。参考以下博文

加固方案。

［附录2］

　　事故发生后，赶到现场的广东省高速公路有限公司总工程师敖道朝解释称：匝道桥的设计货载是“汽车—超20级”，即理论上桥体上有一台55吨的车行驶，同时前后10—15米可以分别有两辆20吨载重的车行驶。“初步判断桥梁垮塌的原因是4辆超载货车紧凑运行，形成巧合的荷载，对桥梁产生了严重的偏压，达到了桥梁坍塌的‘临界点’。四辆货车的载重加上车身自重约有100吨，严重超过了的桥梁载重的设计上限，从理论上说一定会引起桥梁坍塌。”
