Harbin authorities said on Wednesday that overloading caused the collapse of a bridge that killed three and injured five on Aug 24.

Four overloaded trucks, weighing more than 480 metric tons altogether, were on the right side of a 122-meter ramp of the Qunli viaduct project, said Liu Xingming, deputy head of a team investigating the accident.

That made the ramp tilt to one side and crash to the ground, plunging all four trucks to the pavementbelow, Liu told a news conference.

哈尔滨官方周三称，超载是导致大桥垮塌的原因，垮塌事故共造成3死5伤。事故调查组副组长刘新明在新闻发布会上称，总重量超过480吨的四辆超载卡车当时正靠群力高架桥工程的122米长匝道的右侧行驶，这导致了匝道倾斜到一侧，进而垮塌，四辆卡车全部翻落至下面的路面。

【讲解】文中的 overload即指超载，还可以表示超负荷，既可以作动词也可以作名词， overload由over和load合成而来，词缀over指过分，过度，此类的合成词还有 oversupply(供给过多)，overcharge(要价过高，过度充电)，overdraft(透支)等。 文中的collapse指垮塌，崩溃，可作动词或名词，此外ramp表示匝道，viaduct意思是高架桥，pavement意为人行道、路面。
