问题 问答题

(一) 某公共建筑工程,建筑面积22000m2,地下2层,地上5层,层高3.2m,钢筋混凝土框架结构。大堂1至3层中空,大堂顶板为钢筋混凝土井字梁结构。屋面设女儿墙,屋面防水材料采用SBS卷材,某施工总承包单位承担施工任务。

合同履行过程中,发生了下列事件。

事件1:施工总承包单位进场后,采购了110 tⅡ级钢筋,钢筋出厂合格证明资料齐全。施工总承包单位将同一炉罐号的钢筋组批,在监理工程师见证下,取样复试。复试合格后,施工总承包单位在现场采用冷拉方法调直钢筋,冷拉率控制为3%,监理工程师责令施工总承包单位停止钢筋加工工作。

事件2:施工总承包单位根据《危险性较大的分部分项工程安全管理办法》,会同建设单位、监理单位、勘察设计单位相关人员,聘请了外单位五位专家及本单位总工程师共计6人组成专家组,对《土方及基坑支护工程施工方案》进行论证,专家组提出了口头论证意见后离开,论证会结束。

事件3:施工总承包单位根据《建筑施工模板安全技术规范》,编制了《大堂顶板模板工程施工方案》,并绘制了模板及支架示意图,如下所示。监理工程师审查后要求重新绘制。

事件4:屋面进行闭水试验时,发现女儿墙根部漏水,经查,主要原因是转角处卷材开裂,施工总承包单位进行了整改。

指出事件2中的不妥之处,并分别说明理由。

An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving. In the United States, the legal blood alcohol limit is 0.08% for people aged 21 years or older, while people under 21 are not allowed to drive a car with any level of alcohol in their body. A “positive” test result, a result over the legal limit, allows the police to arrest the driver. However, many people who tested positive on the test have claimed that they only drank a “non-alcoholic” energy drink. Can one of these energy drinks really cause someone to test positive on an ABT? Researchers in Missouri set up an experiment to find out.

First, the amount of alcohol in 27 different popular energy drinks was measured. All but one had an alcohol level greater than 0.005%. In nine of the 27 drinks, the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT. They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.

For 11 of the 27energy drinks, the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken. However, alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed. This shows that when the test is taken plays an important role in the test result. The sooner the test is conducted after the consumption of these drinks, the more likely a positive alcohol reading will be obtained.
