问题 问答题

某大型商业建筑工程项目,主体建筑物10层。在主体工程进行到第二层时,该层的100根钢筋混凝土柱已浇注完成并拆模后,监理人员发现混凝土外观质量不良,表面酥松,怀疑其混凝土强度不够,设计要求混凝土抗压强度达到C18的等级,于是要求承包商出示有关混凝土质量的检验与试验资料和其他证明材料。承包商向监理单位出示其对9根柱施工时混凝土抽样检验和试验结果,表明混凝土抗压强度值(28天强度)全部达到或超过C18的设计要求,其中最大值达到了C30即30MPa。
问题

如果承包商承认他所提交的混凝土检验和试验结果不是按照混凝土检验和试验规程及规定在现场抽取试样进行试验的,而是在试验室内,按照设计提出的最优配合比进行配制和制取试件后进行试验的结果。对于这起质量事故,监理单位应承担什么责任,承包方应承担什么责任

答案

参考答案:承包方不按合同标准规范与设计要求进行施工和质量检验与试验,应承担工程质量责任,承担返工处理的一切有关费用和工期损失责任。监理单位未能按照建设部有关规定实行见证取样,认真、严格地对承包方的混凝土施工和检验工作进行监督、控制,使施工单位的施工质量得不到严格的、及时的控制和发现,以致出现严重的质量问题,造成重大经济损失和工期拖延,属于严重失误,监理单位应承担不可推卸的间接责任,并应按合同的约定科以罚金。

A scientist working at her lab bench and a six-old baby playing with his food might seem to have little in common.After all,the scientist is engaged in serious research to uncover the very nature of the physical world,and the baby is,well, just playing…right?Perhaps,but some developmental psychologists()have argued that this“play”is  more like a scientific investigation than one might think.

Take a closer look at the baby playing at the table.Each time the bowl of rice is pushed over the table edge,it

falls in the ground---and, in the process, it belongs out important evidence about how physical objects interact ; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby’s investigation and the scientist’s experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?).

Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language  using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has, for example, unlike the child , Mommy actually doesn’t like Dove chocolate.

Viewing childhood development as a scientific investigation throws on how children learn ,but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort ---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, ”It is not that children are little scientists but that scientists are big children.”

According to some developmental psychologists,()

A. a baby’s play is nothing more than a game.

B. scientific research into babies; games is possible

C. the nature of babies’ play has been thoroughly investigated

D. a baby’s play is somehow similar to a scientist’s experiment
