He told me his parents were both busy and sometimes he stayed at home alone and he had to look after himself."How do you like your school" I asked."Wonderful," said the young man. "It has a tall building and there’re two chemistry labs, two biology labs and three physics ones. And our library is big and there’re plenty of books in it.""I can see you are happy with it.""Yes," answered he. "But our geography teacher often says to himself in class.""So does our new history teacher," I said. "But he doesn’t notice it.

[背景资料] 某混凝土重力坝工程包括左岸非溢流坝段、溢流坝段、右岸非溢流坝段、右岸坝肩混凝土刺墙段。最大坝高43m,坝顶全长322m,共17个坝段。该工程采用明渠导流施工。坝址以上流域面积610.5Km2,属于亚热带暖湿气候区,雨量充沛,湿润温和。平均气温比较高,需要采取温控措施。其施工组织设计主要内容包括: (1)大坝混凝土施工方案的选择。 (2)坝体的分缝分块。根据混凝土坝型、地质情况、结构布置、施工方法、浇筑能力、温控水平等因素进行综合考虑。 (3)坝体混凝土浇筑强度的确定。应满足该坝体在施工期的历年度汛高程与工程面貌。在安排坝体混凝土浇筑工程进度时,应估算施工有效工作日,分析气象因素造成的停工或影响天数,扣除法定节假日,然后再根据阶段混凝土浇筑方量拟定混凝土的月浇筑强度和日平均浇筑强度。 (4)混凝土拌合系统的位置与容量选择。 (5)混凝土运输方式与运输机械选择。 (6)运输线路与起重机轨道布置。门、塔机栈桥高程必须在导流规划确定的洪水位以上,宜稍高于坝体重心,并与供料线布置高程相协调,栈桥一般平行于坝轴线布置,栈桥墩宜部分埋入坝内。 (7)混凝土温控要求及主要温控措施。 混凝土浇筑的施工过程包括哪些
