某小区共有40栋砖混住宅楼工程,属非地震区,分两期组织流水施工,每期20栋,屋面防水为两层3mm+3mmSBS卷材。先期施工的20栋楼建成后不久,发现在纵墙的两端出现斜裂缝,多数裂缝通过窗口的两个对角,裂缝向沉降较大的方向倾斜,并由下向上发展。裂缝集中在墙体下部,向上逐渐减少,裂缝宽度下大上小,其数量及宽度随时间而逐渐发展。此时,后期施工的20栋楼刚刚开工,现场监理单位组织施工、设计、勘察单位进行现场质量问题分析,形成质量事故处理报告,报告中决定后期的20栋楼从两方面来防治裂缝的发生:一是加强基底处理;二是提高上部结构的刚度,增强墙体抗剪强度。监理工程师要求施工单位根据这两条原则提出具体的防控措施;并对先期的20栋中的裂缝提出处理措施。后期20栋屋面卷材施工正值盛夏,施工完毕后立刻发现屋面卷材起鼓,且大小鼓泡连片,小的数十毫米,大的直径可达300mm以上。

试分析屋面卷材起鼓的成因?

答案

参考答案:

本案例中屋面卷材起鼓原因:

在卷材防水层中粘结不实的部位,窝有水分和气体;正好该工程屋面卷材施工正值盛夏,气温相对比较高,当受到太阳照射后,体积膨胀,造成鼓泡。

The clock rules our lives. The more we try to save time, the less time we seem to have. In every area of our lives we are doing things faster. And many of us live in towns and cities which are getting noisier and more stressful as each day passes. But now a worldwide movement, whose aim is to slow life down, has started. Its supporters are people who believe that a happier and healthier way of life is possible.

The Slow Food movement was founded the day that an Italian journalist, Carlo Petrini, saw that McDonald’s had opened a restaurant in a beautiful square in Rome. He thought it was sad that many people today live too quickly to sit down for a proper meal and only eat much fast food. He decided that he had to try to do something about it and so he started the Slow Food movement. Slow Food has become a global organization ever since and now has more than 80,000 members in 100 countries.

Slow Food also encourages people to eat local and regional food, to use local shops and markets, to eat out in small family restaurants, and to cook with traditional recipes.

The idea of Slow Cities was inspired by the Slow Food movement. The aim of Slow Cities is to improve people’s quality of life. Towns which want to become a Slow City have to reduce traffic and noise, increase the number of green areas, plant trees, build pedestrian zones, and promote local businesses and traditions. Now it has spread to other countries all over the world, from the UK to Japan and Australia. There are now 135 Slow Cities in 24 countries across the world that have been named since founding of the organization in 1999. Gao Chun County, in east China’s Jiangsu Province, is expected to be named the first “Slow City” in China next year.

“Slow Cities are about having a community life in the town,” said a local resident. “It is not ‘slow’ as in ‘stupid’. It is ‘slow’ as in the opposite of ‘worried’ and ‘stressful’.”

But not everybody is happy. For teenagers, who have to go 25km to Norwich, the nearest city, to buy CDs, living in a Slow City is not very attractive. “It’s all right here,” says Lewis Cook, 16. “But if you want excitement, you have to go to Norwich. We need more things here for young people.”
