        表1-7 分部分项工程量计算表

答案

参考答案:
1.建筑面积=S首层+S二层
S二层=S首层-S门斗
建筑面积=2S首层-S门斗
=2[(35.1+2×0.37)(12.3+2×0.37)-2.1×(3.6+3.6)-(8.4×2+6)× 4.2]-2.1×(5.1-0.12+0.37)
=701.71(m2)
2.场地平整的工程量(m2)
S场地=S首层=(35.1+2×0.37)(12.3+2×0.37)-2.1×(3.6+3.6)-(8.4×2+6)×4.2
=356.47(m2)
3.外墙毛石基础的工程量(m3)
V外墙毛石基础=外墙毛石基础断面积×外墙毛石基础中心线长度
外墙毛石基础断面积=1.2×0.5+(0.105+0.37+0.12+0.105)×0.8=1.16(m2)

外墙毛石基础断面积=1.2×0.5+(1.2-2×0.25)×0.8=1.16(m2)
外墙毛石基础中心线长度



外墙毛石基础中心线长度


V毛石=1.16×95.8=111.13(m3)
4.外墙砖基础工程量(m3)
因为基础与墙身使用不同材料,且位于设计室内地坪以下650mm,所以应以设计室内地坪为界来划分砖基础和砖墙,设计室内地坪以下为砖基础,设计室内地坪以上为砖墙。
V外墙砖基=外墙砖基础断面积×外墙砖基础中心线长度
外墙砖基础断面积=0.49×0.65=0.3185(m2)
外墙砖基础中心线长度=外墙毛石基础中心线长度
=95.8(m)
V外墙砖基=0.3185×95.8=30.51(m3)
5.外墙砌砖工程量(m3)
V外墙砖基=外墙断面面积×外墙中心线长度±△
因为屋面为平坡面,所以外墙高度算至混凝土板底,且以设计室内地坪为界。
外墙断面积=外墙厚度×外墙高度
=0.49×(7.8-0.12)(其中0.12为板厚)
=3.7632(m2)
外墙中心线长度=外墙毛石基础中心线长度=95.8m
+△=V墙垛=1.18(m3)
-△=V+V+V混凝土过梁+V混凝土过梁+V暖气包壁龛
V=4.6×3.07×0.49+1.5×2.7×0.49×2=10.89(m3)
V=2.7×2.1×0.49×10+2.4×2.1×0.49×16+2.1×2.1×0.49×4+1.2×0.8× 0.49×3+1.5×2.1×0.49×1+1.8×2.1×0.49×2
=47.03706(m3)
V混凝土圈梁+V混凝土过梁=10.12(m3)
V暖气包壁龛=4.54(m3)
V外墙砌砖=3.7632×95.8+1.18-10.89-47.03706-10.12-4.54
=289.11(m3)
6.现浇三跑混凝土楼梯(C20)工程量(m2)。
因为楼梯井宽度为1680mm,大于500mm,所以应扣除全楼梯井面积。
S现浇混凝土楼梯=S楼梯间-S楼梯井
=(5.1-2×0.12)×(4.2+0.12-0.12)-1.68×(2.76-0.12)
=15.98(m2)
7.门厅水磨石地面工程量(m2)
门洞开口部分不并入相应的工程量内。
S水唐石地面=(5.1-2×0.12)×(3.9-0.12+0.12)=18.96(m2)
8.⑤—⑥首层复合本地面工程量(m2)
门洞开口部分并入相应的工程量内计算。
S⑤—⑥首层复合木地面=(8.4-2×0.12)×(2.1+3.9-2×0.12)+0.9×0.49×2
=47.88(m2)
9.首层三间教室内墙抹灰工程量(m2)
S教室A抹灰=[(8.4-2×0.12)×2+(2.1+3.9-2×0.12)×2]×(3.9-0.12)-2× 0.9×2.4-2×2.7×2.1-2.1×1.2
=88.14(m2)
S教室B抹灰=[(8.4-2×0.12)×2+(2.1+3.9-2×0.12)×2]×(3.9-0.12)-2× 0.9×2.4-2×2.7×2.1-2.1×1.2
     =88.14(m2)
S教室C抹灰=[(6-2×0.12)×2+(2.1+3.9+2.1-2×0.12)×2]×(3.9-0.12)- 1.5×2.7-2.7×2.1-2×2.4×2.1
  =83.17(m3)
S首层教室抹灰=88.14+88.14+83.17=259.45(m2)
10.排水管的工程量(m)
L排水管=[7.8-(-0.45)]×7=41.25(m)

     Do you ever find yourself getting really angry for almost no reason? Or suddenly feeling down

without knowing why? Going from sadness to anger to joy in a matter of minutes can make many

teens feel as though they're losing their control. But why is the feeling of being on an emotional roller

coaster (急转突变) so common among teens?

     Dealing with constant change and pressure is part of the answer. Maybe you're starting a new

school and not able to see old friends as much. Getting good grades or wanting to be better in sports

or other activities can be a concern for many teens. It might feel as though there just isn't enough time

to do everything.

     Being a teen means struggling with identity and selfimage. Being accepted by friends feels

extremely important. Teens also may notice, for the first time, a sense of distance from parents and

family. You may feel you want to be on your own and make your own decisions, but it can also

seem overwhelming (压倒的) and even a bit lonely at times. As fun and exciting as this time is, it also

can be a time of confusion and conflict.

     Another important cause for mood swings is biology. When puberty (青春期) begins, the body

starts producing sex hormones. These hormones cause physical changes in the body. But in some

people, they also seem to cause emotional changes-the ups and downs that sometimes feel out of

control.

     Feeling irritable or shorttempered can be signs of depression.  So can feelings of boredom or

hopelessness. Many people think of depression as feeling sad, but depression can also bring feelings

of moodiness, impatience, anger. When depression gets in the way of enjoying life or dealing with

others, that's a sign you need to do something about it, like talking to a counselor or therapist (治疗

专家) who can help you deal with it.

     Here are some things you can do that might make those bad moods a bit easier to handle: recognize

you're not alone, catch your breath, count to 10, talk to people you trust, exercise, cry or wait.

 1. From the passage, we can infer that the teens' emotional changes are ________.

A. abnormal                          

B. reasonable

C. predictable                        

D. natural

2. How many reasons does the author refer to in the passage for children's emotional changes? 

A. Two.                              

B. Three.

C. Four.                              

D. Five.

3. What does the passage mainly talk about?

A. Why people are in bad mood.

B. What the result of depression is.

C. Bad mood can cause bad effects.

D. It's important to be dependent.

4. What does the underlined word "irritable" in the fifth paragraph mean?

A. Upset.                            

B. Angry.

C. Unhappy.                          

D. Impatient.
