题目:

[案例三]

背景


某高速公路跨线大桥(7×20m+65m+7×20m+5×20m)引桥上部结构为预应力钢筋、混凝土箱梁,后张法施工,采用预制吊装施工工艺。预制场布设在桥位附近荒地,地势平坦,承包人根据工期要求设置10个预制台座,预制场整平压实后,浇筑台座混凝土,抹光整平检验合格后预制箱梁。
为防止箱梁预拱度出现偏差,承包人严格控制模板施工质量和立模高程;严格控制张拉时箱梁混凝土强度和存梁时间。箱梁预制过程中主要检验了箱梁混凝土强度和箱梁几何尺寸,以确保梁体质量,箱梁达到规定强度后移至存梁区,箱梁按两层水平存放,层与层之间支垫枕木。
为加快工程进度,该大桥承包人报监理工程师批准并于业主认可后将部分箱梁移运、安装工程分包给具有相应资质的分包人,并签订分包合同。
为保证箱梁的安装质量,主要检验了箱梁安装竖直度和箱梁顶面纵向高程。安装过程中发生了1片箱梁掉落地面的事故,幸未造成人员伤亡和设备损坏。该片箱梁经检查后作报废处理,直接经济损失约6万元人民币,承包人将事故报告监理工程师,经同意后继续施工。

问题:


判断背景资料中所列箱梁掉落地面情况属于哪类质量事故按照工程质量事故报告制度的要求,承包人对该事故的处理方法是否妥当请说明理由。

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological(生态的) disaster area. Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.

For thousands of years, Polynesian people lived the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.

However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.

Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸盐)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which a very important fertilizer for farming. The company began mining the phosphate.

A phosphate mine is not a hole in the ground; it is a strip mine(带状矿). When a company strip-mines, it removes the top layer(层) of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.

In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.

Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.
