China has become Volvo's third largest market, with more of its car models to go on sale in the world's largest auto(汽车) market this year, Chief Executive Office (CEO) of Volvo Cars China said in Tianjin.

Alexander Klose, CEO of Volvo Cars China, told Xinhua at the Ninth Tianjin International Automobile Trade Show, being held from Friday to Wednesday.

Klose said Volvo Cars had entered a new time of fast development, adding that its sales volume in China roared in 2010.

Up to the end of September, Volvo's global sales volume was up 12.5 percent year on year(同年比), compared with 52 percent year-on-year rise in China, he said.

Two new Volvo sales centers opened in Beijing within merely one week in early October, about two months after east China's ZhejiangGeely Holding Group Co acquired(购得)the Swedish brand from the US auto giant Ford for $1.5 billion in early August.

Klose said he was confident of seeing tremendous(巨大的) growth in China's auto market in the next five years. "As the Chinese government has increased the tax rate for large displacement (排量)cars already, we now have a lot of cars below three liters(升), and I think we'll stick to that strategy, as you can see now the XC60 which was introduced today is just two liters," he said.

"As the technology advances, we'll probably even see 1.6 liter engines or 1.5 liter engines in the future," he added.

Volvo Cars is not the only automaker hoping to take advantage of China's rapidly growing auto market.

Bentley, the famous British luxury(豪华) carmaker, will open a new sales center in China at Tianjin Thursday, which is the 11th one in China, according to a press release(新闻发布) by Shanghai-based Zenith Integrated Communications Corp (Zenith) Saturday at the auto show.

Zenth is the public relations agent of Bentley in China. The automaker has sold 421 limousines(大型豪华轿车) to China in 2009, and the goal for 2010 is 777, the release said.

问答题 案例分析题

背景

由某企业承建某多功能现代化商务综合大厦,地上46层,地下3层,全现浇钢筋混凝土框架一剪力墙结构,主体结构采用泵送混凝土等新技术。建筑物周边都十分接近规划用地红线,周边建筑及地下管线对因工程基坑开挖引起地层变形移动影响十分敏感,且基坑北面邻近地铁。该工程地下室基坑开挖深度较大,为确保基坑开挖安全编制了专项施工方案,专家论证并由安全总监签字确认后实施。该地下室位于总厚度达40多米的淤泥质土之中,根据本工程的特点,经多方案比较,决定基坑围护结构采用80cm厚的地下连续墙,而支护结构则为五道钢筋混凝土水平支撑的总体方案。经验算,可以满足结构变形和稳定要求,确保地下室开挖施工不至于影响地铁的正常运行、周边道路、建筑物及各种地下管线的正常使用。在工程施工中发生如下事件:

事件一:本工程地下水位较高,约为-0.5m,开挖范围位于淤泥质土体内,含水量大,施工必须事前采取降水措施,因基坑围护是采用地下连续墙,具有较好的挡水和抗渗性能。结合实际情况,决定采用轻型井点降水并编制了降水施工方案。

事件二:根据地质勘察资料、上部结构形式、荷载和施工条件等情况,基础施工采用人工挖孔扩底灌注桩与平板式筏形基础,板厚2m,桩基承台连同地下室的筏形基础同时展开施工。基础底板厚2m,桩基承台厚1.8m,混凝土强度等级C40,抗渗等级P8。由于承台和筏板混凝土浇筑量大,在开始阶段施工中出现了少许裂缝。为确保施工质量,项目部制定了以下控制裂缝的措施:

(1)优先选用低水化热的普通硅酸盐水泥拌制混凝土,并适当加人木质素磺酸钙减水剂。

(2)在保证混凝土设计强度等级的前提下,适当提高水灰比,减少水泥用量。

(3)降低混凝土的浇筑温度,控制混凝土内外温差在30℃以内。

(4)分层分块逐步浇筑,加强养护,及时对混凝土进行覆盖保温、保湿材料。

(5)预埋冷却管,通人循环水将混凝土内部降温。

事件三:在进行办公楼大厅顶盖模板支架预应力混凝土空心板现场浇筑施工时,发生模板支撑体系坍塌事故,造成6人死亡、12人受伤。经有关部门调查,造成事故主要原因是模板支架搭设质量不符合要求;现场搭设模板支架中使用的部分钢管材料存在质量缺陷;施工现场管理存在严重问题。事后,建设行政主管部门对该施工企业作了相应的行政处罚,公安机关依法对有关责任单位的涉案人员追究刑事责任。

事件三工程事故可定为哪级事故?并说明理由。
