1、【建筑测量】形成性考核册作业答案建筑测量作业1一、 填空题1.、测量工作的基本原那么是程序上“由整体到局部”；步骤上“先控制后碎部”：精度上“从高级到低级”。、方位角是门某标准方向起始，顺时针至一条直线的水平角，以过直线起点的平面坐标纵轴平行线指北端为标准方向 的方位角_为坐标方位角。坐标方位角范国0360,象限角取值范围为090,为了说明直线所在的象限，在角值前 应加注直线所在象限的名称，3、高程是指地面点沿铅垂线到一定基准面的距离。测盘中定义以大地水准面作基准面的高程为绝对高程,以其它任意 水准面作基准面的高程为相对高程。地面任意两点之间的高程之差称为直差。无论采用绝对高程还是相对高程，两

2、点 间的高差总是不变的。如果何为正时,说明B点高了A点。4、水准测吊的甚本原理是利用水准仪提供的水平视线测定地面两点之间的高差,推算未知点高程一种方法,5、水准仪的粗略整平是指旋转脚螺旋使圆水准气泡居中；水准仪的精确整平是指旋转微颈螺旋，使水准管气泡居中。 6、水准漓量的水准路线分为附合水准路线、闭合水准路线、支水准路线。7、使用微倾式水准仪的操作卷课粗略整平、瞄准标尺、精确整五争尺读数二、名词解释和简答题1、地面点的平面位置如何确定？测量上的直角坐标系有哪些？他们是如何定义的？答：地面点的平面位置可用二维球面或平面坐标确定。测量上的直角坐标系有：高斯平面直角坐标系，独立平面 直角坐标系.高斯

3、投影是一种横轴椭圆柱投影，即设想用一个椭圆柱套住地球椭球体，使椭圆柱的中轴横向通过椭球 体的中心，将椭球面I的，点:位和图形投影到椭圆柱的面上，然后将椭圆柱沿通过南、北极的母线展开成平面，即得到 高斯投影平面，在此平面上，椭球体和椭圆柱相切的一条子午线和赤道的投影为两条相互正交的宜线，即构成高斯平 面直角坐标系。在水平面上设一坐标原点，以过原点的南北方向为纵轴（向北为正，向南为负），东西方向为横轴（向 东为正，向西为负），建立的坐标系为独立的平面直角坐标系。2、何谓水准面？何谓大地水准面？地面点的第三维坐标是什么？答：所谓水准面是假想处丁静止状态的海水面延伸穿过陆地和岛屿，将地球包围起来的封闭

4、曲面。所谓大地水准面是通过平均海水面的水准面，因而大地水准面具有惟一性。地面点的第三维坐标是高程。3、在距离测量及高程测量中用水平面代替水准面的限度分别是多少？答：当地形图测绘或施工测量:的面积较小时，可将测区范围内的椭球面或水准面用水平面来代替，这将使测量的 计算和绘图大为简便，但必须有一定的限度。距离测量时，可将10km长的区域作为距离测量时用水平面代替水准面的 限度，在一般测量工作中，有时这一限度可放宽至25km长的区域：在一般高程测量中，也只能以距离100m为用水平 面代替水准面的限度。4、何谓水准点？何谓转点？尺垫起何作用？什么点上才用尺垫？水准点要用尺垫吗？答：用水准测量方法测定的

5、高程控制点称为水准点，常以BM表示。所谓转点是临时设置，用于传递高程的点，转点的作用就是传递高程。尺垫般由铸铁制成，呈三角型，尺垫，其 中央有一突出圆顶，测量时用于支承标尺。转点上应放置尺垫.水准点不放置尺垫。5、水准仪主要由哪几局部的组成？各有何作用？何为望远镜的放大倍率？何为水准管分划值？答：水准仪主要由望远镜、水准器和基座三个局部组成。里远镜由物镜、目镜、对光透镜和十字丝分划板等 组 成，主要用于照准目标、放大物象和对标尺进行读数。水准器是用整平仪曙的装置。基座通过中心螺旋将仪器与三 角架相连接.旋转三个脚螺旋调节圆水准气泡居中，即可使仪器粗略整平。望远镜的放大倍率：放大后的虚象对眼睛构

6、成的视角B与眼睛直接观测目标构成的视角a之比，即放大后的虚 象与用眼睛直接看到目标大小的比值。水准管分划值：相邻分划线间的圆弧所对应的圆心角值。6、什么是视差？它是怎样产生的？如何消除？答：所渭“视差”，是当眼睛在目镜端上、下微动时，看到十字丝与目标的影像相互移动的现象。其产生的原因 是目标的实象未能刚好成在十字丝.平而上。视差的存在会增大标尺读数的误差，消除的方法是再旋转物镜对光螺旋， 重复对光，直到眼暗上、下微动时标尺的影像不再移动为止。7717、水准测量为什么要求前后视距相等？答：前后视距相等可消除,角误差、地球曲率和大气折光的误差。8、水准测量外业中有哪些测站检核和计算检核？答：测站检

7、核的方法有：】)变仪高法。2)双面尺法。 计算检核：所有测站的后视读数之和与前视读数之和 的差值等于测站高差之和，UP： h = a-b9、水准仪主要轴线之间应满足的几何条件是什么？各起什么作用？水准仪的主要轴线仃望远镜视准轴CC、水准管轴、圆水准轴此外还有仪器的竖轴叱。它们之间应满足以 下几何条件：1 )圆水准轴平行于仪器的竖轴，即：2 )十字丝丝乖宜于以轴，即十字丝横丝,叱；3 )水准管轴平行于视准轴，即CC.满足L L VV,使圆水准气泡居中时，6轴基本铅直，视准轴粗平。使十字丝横丝垂宜于也轴。当哙轴铅直时，横 丝处于水平，横丝上任何位置读数均相同。满足条件LL(:C,使水准管气泡居中时
