Human beings are animals. We breathe, eat and digest, and reproduce the same life (1) common to all animals. In a biological laboratory, rats, monkeys, and humans seem very much the same.
However, biological understanding is not enough: (2) itself, it can never tell us what human beings are. (3) to our physical equipment--the naked human body--we are not an (4) animal. We are tropical creatures, (5) hairless and sensitive to cold. We are not fast and have neither claws nor sharp teeth to defend ourselves.We need a lot of food but have almost no physical equipment to help us get it. In the purely physical (6) , our species seems a poor (7) for survival.
But we have survived--survived and multiplied and (8) the earth. Some day we will have a (9) living on the moon, a place with neither air nor water and with temperatures that mm gases into solids. How can we have done all these things. Part of the answer
A. processes
B. acts
C. modes
D. procedures
背景
某新建办公楼工程,主楼建筑面积29600m2的,地上16层,地下1层,基础埋深4m,现浇混凝土框架一剪力墙结构。附楼建筑面积5000m2混合结构,地上3层。地下防水采用防水混凝土附卷材防水,屋面采用卷材防水,室内采用涂料防水。土方开挖采用放坡形式。预制桩地基,筏板基础。某施工总承包单位中标后成立了项目部组织施工。施工过程中发生如下事件:
事件一:土方开挖过程中,边坡局部塌方,使地基土受到扰动,承载力降低,严重了影响建筑物的安全。监理单位认为原因是基坑开挖坡度不够。要求清除塌方后作临时性支护措施。
事件二:预制桩施工中桩身断裂。桩在沉人过程中,桩身突然倾斜错位,桩尖处土质条件没有特殊变化,而贯入度逐渐增加或突然增大;同时,当桩锤跳起后,桩身随之出现回弹现象。项目部分析原因是桩入土后,遇到大块坚硬的障碍物,把桩尖挤向一侧。采取的措施是在稳桩过程中及时纠正垂直,接桩时要保证上下桩在同一纵轴线上,接头处要严格按照操作规程施工。监理工程师认为分析不够,措施不全。
事件三:主楼地上一层楼板钢筋验收时,发现柱、板主筋错位,个别保护层不够。项目部分析原因是钢筋未按照设计或翻样尺寸进行加工和安装。防治措施是现场钢筋加工应严格按照设计和现场翻样的尺寸进行加工和安装。监理工程师认为分析不够,措施不全。
事件四:一层电梯侧墙模板拆除后混凝土表面出现麻面、露筋、蜂窝、孔洞现象。项目部分析原因是表面不光滑、安装质量差,接缝不严、漏浆,模板表面污染未清除;木模板在混凝土人模之前没有充分湿润,钢模板脱模剂涂刷不均匀;钢筋保护层垫块厚度或放置间距、位置等不当。防治措施是:模板使用前进行表面清理,保持表面清洁光滑,钢模应保证边框平直,组合后应使接缝严密,必要时可用胶带加强,浇混凝土前应充分湿润或均匀涂刷脱模剂。监理工程师认为分析不够,措施不全。
事件五:二层顶板发现混凝土收缩裂缝。项目部分析原因是混凝土原材料质量不合格,如骨料含泥量大等;水泥或掺合料用量超出规范规定。防治措施是选用合格的原材料。监理工程师认为分析不够,措施不全。
