教材课后习题参考答案

教材课后习题参考答案1 稻草人1. 首先抓住重点句,仔细读课文,理解课文内容,体会稻草人情感的变化,感受他心灵的美好和善良。

然后,理清各部分、各段的主要内容,把相关的故事情节连贯起来,转化成自己的语言讲出来。

2. 体现稻草人感情变化的语句有:第3自然段2、3句和后3句,第4自然段后4句,第7自然段,第8自然段第2句,第9自然段最后一句,等等。

稻草人开始见庄稼长得壮实,所以心里高兴,替命运悲惨的主人感到欣慰;后来见小蛾在叶尖产子,觉得灾害将临,所以心里着急,拼命想把消息通知主人;最后看到稻子遭到祸害,心中十分悲伤,为主人伤心流泪。

3. 本文中,稻草人不仅尽责尽职,还替主人高兴,为主人担忧,甚至想“跳过去,把那灾害的根苗扑灭了”,这都表现了他心地善良,富有同情心,灵魂高尚的精神品质,他是值得我们喜爱和学习的。

4. 略2 寓言两则1. 略2. 《自相矛盾》的意思是一个人说话做事前后矛盾,有些言过其实,自己说的和做的往往不一致,最后搬起石头砸到了自己的脚。

它告诉我要言行一致,实话实说。

《画蛇添足》是说一个人做事总爱节外生枝,卖弄小聪明,结果事情非但不能做好,反而弄巧成拙,惹出很多麻烦。

它告诉我做事要实事求是,不要卖弄小聪明。

3. 略3 卖火柴的小女孩儿1. 略2. 文中小女孩儿共五次擦燃火柴,分别看到了烧得旺旺的大火炉、香喷喷的烤鹅、美丽的圣诞树、慈祥的奶奶和随奶奶升入天堂五个幻觉。

课文中感人的地方很多,比如,小女孩儿五次美好的幻觉,在大年夜被冻死的情景,等等。

3. 第一个“幸福”是指小女孩儿临死时是在美好的幻觉中度过的,是幸福的;第二个“幸福”指小女孩儿死了就没有寒冷、饥饿和痛苦了,就彻底幸福了。

这句话的意思是,活着没有人会关心她,只能忍冻挨饿,一生痛苦,只有死才能得到解脱,表达了作者对穷苦人民的深切同情和对贫富悬殊的社会的强烈不满。

4. 略4*刺猬汉斯1. 课文主要讲有一个富有的农夫,他的妻子生了个怪儿子——刺猬汉斯。

工程荷载与可靠度设计原理习题解答(终审稿)

工程荷载与可靠度设计原理习题解答(终审稿)

工程荷载与可靠度设计原理习题解答公司内部档案编码:[OPPTR-OPPT28-OPPTL98-OPPNN08]《工程荷载与可靠度设计原理》习题解答1 荷载与作用什么是施加于工程结构上的作用荷载与作用有什么区别结构上的作用是指能使结构产生效应的各种原因的总称,包括直接作用和间接作用。

引起结构产生作用效应的原因有两种,一种是施加于结构上的集中力和分布力,例如结构自重,楼面的人群、家具、设备,作用于桥面的车辆、人群,施加于结构物上的风压力、水压力、土压力等,它们都是直接施加于结构,称为直接作用。

另一种是施加于结构上的外加变形和约束变形,例如基础沉降导致结构外加变形引起的内力效应,温度变化引起结构约束变形产生的内力效应,由于地震造成地面运动致使结构产生惯性力引起的作用效应等。

它们都是间接作用于结构,称为间接作用。

“荷载”仅指施加于结构上的直接作用;而“作用”泛指使结构产生内力、变形的所有原因。

结构上的作用如何按时间变异、空间位置变异、结构反应性质分类结构上的作用按随时间变化可分永久作用、可变作用和偶然作用;按空间位置变异可分为固定作用和自由作用;按结构反应性质可分为静态作用和动态作用。

什么是荷载的代表值它们是如何确定的荷载代表值是考虑荷载变异特征所赋予的规定量值,工程建设相关的国家标准给出了荷载四种代表值:标准值,组合值,频遇值和准永久值。

荷载可根据不同设计要求规定不同的代表值,其中荷载标准值是荷载的基本代表值,其它代表值都可在标准值的基础上考虑相应的系数得到。

2 重力作用成层土的自重应力如何确定地面以下深度z处的土体因自身重量产生的应力可取该水平截面上单位面积的土柱体的重力,对于均匀土自重应力与深度成正比,对于成层土可通过各层土的自重应力求和得到。

土压力有哪几种类别土压力的大小及分布与哪些因素有关根据挡土墙的移动情况和墙后土体所处应力状态,土压力可分为静止土压力、主动土压力和被动土压力三种类别。

土的侧向压力的大小及分布与墙身位移、填土性质、墙体刚度、地基土质等因素有关。
