2005年底,全国城镇房屋建筑面积中非住宅建筑面积为( )。

A.58.62亿平方米

B.56.82亿平方米

C.52.86亿平方米

D.53.86亿平方米

答案

参考答案:B

解析: 全国城镇房屋建筑面积164.51亿平方米减去其中住宅建筑面积107.69亿平方米,即为非住宅建筑面积,164.51-107.69=56.82亿平方米。

问答题 案例分析题

背景材料:

某公路路面工程,里程桩号为K5+000~K29+000,总长度为24km。路面结构层分为级配砾石底基层、水泥稳定碎石基层、沥青面层(单层)。建设单位(业主)希望施工单位尽可能用最短时间完成该路面工程施工。施工单位根据自己的能力准备组织2个路面施工队平行施工以完成该路面工程。每个路面施工队的施工能力相同,各完成12km。根据以往类似工程的施工经验,底基层专业队组(班组)施工进度(速度)200m/d(已经包含各种影响,下同);水泥稳定碎石基层专业队组施工进度150m/d,养生时间至少7d,所需工作面的最小长度为1000m;沥青面层专业队组施工进度为160m/d,所需最小工作面长度1200m。要求施工单位用最快方式,根据上述给定条件组织路面工程线性流水施工。以下是施工单位所作的计算和施工进度计划横道图:(1)各结构层工作的持续时间计算为底基层60d,基层80d,面层75d。(2)底基层与基层之间逻辑关系STS(开始到开始)搭接关系,搭接时距计算结果为1000/200=5d。(3)基层与面层之间的逻辑关系STS搭接关系,搭接时距计算结果为1200/150=8d,考虑到基层的养生至少7d,所以基层与面层的开始到开始时间间隔为8+7=15d。(4)根据以上计算结果,路面工程的总工期=5+15+75=95d,其施工进度计划横道图表示如下:

评价该施工单位所进行的计算正确性以及进度计划安排的合理与否。

1)各工序的持续时间的计算是正确否?有错请改正。

2)底基层与基层之间的搭接关系选择正确否?为什么?有错请改正。

3)底基层与基层之间的搭接时距计算正确否?有错请改正。

4)基层与面层之间的搭接关系选择正确否?为什么?有错请改正。

5)基层与面层之间的搭接时距计算正确否?有错请改正。

6)路面工程的总工期的计算以及其施工进度计划横道图表示正确否?有错请改正。
