Chinese people are now spending more time surfing the net than watching TV, according to results of a survey by the Chinese Academy of Social Sciences (CASS) published Thursday.

The survey, of citizens of five Chinese cities, found that 79 percent of interviewees use the internet for information, and 55.1 percent to read news on the internet. About 63 percent of the interviewees use e-mail. The average times spent surfing the net and watching TV were 2.73 hours and 1.29hours, respectively.

Only 10.4 percent reported use the internet primarily to send and receive email; 65.9 percent read online news; 62.2 quite often play games on-line. More and more people have taken an interest in the entertainment opportunities online. Up to 56.5 percent of interviewees quite often download music, and 53.5 percent get entertainment messages from the internet.

Yet the survey found that television is still the dominant mass medium. Seventy-nine percent of interviewees choose to watch TV to get information, and another 75 percent take newspapers as important as TV.

Five major web sites in the Chinese language, namely Sina, Sohu, Netease, Baidu and Yahoo are still ranked top ones by web users, and those that voted for Sina as the best among them were 30.9 percent.

问答题

(三)


某市中心区新建一座商业中心,建筑面积26000m2,地下2层,地上16层,1至3层有裙房,结构形式为钢筋混凝土框架结构,柱网尺寸为8.4 m×7.2m,其中2层南侧有通长悬挑露台,悬挑长度为3m。施工现场内有一条10kV高压线从场区东侧穿过,由于该10kV高压线承担周边小区供电任务,在商业中心工程施工期间不能改线迁移。
某施工总承包单位承接了该商业中心工程的施工总承包任务。该施工总承包单位进场后,立即着手进行施工现场平面布置:
(1)在临市区主干道的南侧采用1.6m高的砖砌围墙作围挡;
(2)为节约成本,施工总承包单位决定直接利用原土便道作为施工现场主要道路;
(3)为满足模板加工的需要,搭设了一间50m2的木工加工间,并配置了一只灭火器;
(4)受场地限制在工地北侧布置塔吊一台,高压线处于塔吊覆盖范围以内。
主体结构施工阶段,为赶在雨季来临之前完成基槽回填土任务,施工总承包单位在露台同条件混凝土试块抗压强度达到设计强度的80%时,拆除了露台下模板支撑。主体结构施工完毕后,发现2层露台根部出现通长裂缝,经设计单位和相关检测鉴定单位认定,该裂缝严重影响到露台的结构安全,必须进行处理,该事故造成直接经济损失8万元。

问题


指出施工总承包单位现场平面布置(1)~(3)中的不妥之处,并说明正确做法。
