2、經(jīng)緯儀碎部點(diǎn)測(cè)量的基本工作有哪些？答：經(jīng)緯儀碎部點(diǎn)測(cè)量的基本工作有：（1）安裝經(jīng)緯儀并對(duì)中整平，測(cè)儀器高度，后視相鄰導(dǎo)線點(diǎn)，確定導(dǎo)線方向，并將水平讀盤讀數(shù)歸零。（2）瞄準(zhǔn)待測(cè)目標(biāo)，讀取上、中、下絲讀數(shù)，讀取水平讀盤和豎直讀盤讀數(shù)。（3）分別計(jì)算水平角、豎直角、水平距離、高差和碎部點(diǎn)高程。（4）按比例將碎部點(diǎn)展繪到圖紙上。

3、測(cè)量水平角時(shí)，為什么要用盤左、盤右兩個(gè)位置觀測(cè)？答：為了消除儀器視準(zhǔn)軸誤差和橫軸不水平誤差，提高精度，防止粗差。

4、什么是比例尺精度？它在測(cè)繪工作中有何作用？答：相當(dāng)于圖上0.1㎜的實(shí)地水平距離稱為比例尺精度，在測(cè)圖時(shí)用來(lái)決定測(cè)區(qū)地面的測(cè)量詳細(xì)程度，取舍地物，在規(guī)劃設(shè)計(jì)用圖時(shí)，用來(lái)選擇合適的比例尺地形圖。

5、測(cè)量工作中怎樣檢查視差，如何消除視差？答：測(cè)量工作中產(chǎn)生視差的原因是由于物鏡調(diào)焦不完善，使目標(biāo)實(shí)像不完全成像在十字絲平面上；在目鏡端觀測(cè)者眼睛略作上下少量移動(dòng)，如發(fā)現(xiàn)目標(biāo)也隨之相對(duì)移動(dòng)，即表示有視差存在；再仔細(xì)進(jìn)行物鏡調(diào)焦，直至成像穩(wěn)定清晰。

6、說(shuō)明測(cè)量高斯平面坐標(biāo)系與數(shù)學(xué)笛卡爾坐標(biāo)系的區(qū)別。

答：測(cè)繪中高斯平面坐標(biāo)系以縱軸為X軸,表示南北方向,向北為正；橫軸為Y軸,表示東西方向,向東為正；象限順序順時(shí)針?lè)较蚺帕?這是由于測(cè)量工作中以極坐標(biāo)表示點(diǎn)位時(shí)其角度值是以北方向?yàn)榘错槙r(shí)針?lè)较蛴?jì)算,而解析幾何中則從橫軸起按逆時(shí)針?lè)较蛴?jì)算的緣故。

7、施工測(cè)量的目的是什么？它包括哪些工作內(nèi)容？

答：施工測(cè)量，指的是在工程施工階段進(jìn)行的測(cè)量工作，是工程測(cè)量的重要內(nèi)容。包括施工控制網(wǎng)的建立、建筑物的放樣、竣工測(cè)量和施工期間的變形觀測(cè)等。

施工測(cè)量(測(cè)設(shè)或放樣)的目的是：將圖紙上設(shè)計(jì)的建筑物的平面位置、形狀和高程標(biāo)定在施工現(xiàn)場(chǎng)的地面上，并在施工過(guò)程中指導(dǎo)施工，使工程嚴(yán)格按照設(shè)計(jì)的要求進(jìn)行建設(shè)。?

8、測(cè)量豎直角時(shí)，如何消除豎盤指標(biāo)差?答：測(cè)量豎直角時(shí)，采用盤左、盤右位置觀測(cè)，取觀測(cè)值的平均值作為豎直角，以消除豎盤指標(biāo)差的誤差影響。

9、測(cè)圖前有哪些準(zhǔn)備工作?答：測(cè)圖前除做好儀器、工具和有關(guān)測(cè)量資料的準(zhǔn)備外，還應(yīng)進(jìn)行控制點(diǎn)的加密工作（圖根控制測(cè)量），以及圖紙準(zhǔn)備、坐標(biāo)格網(wǎng)繪制和控制點(diǎn)的展繪等準(zhǔn)備工作。用比例尺在圖紙上量取相鄰導(dǎo)線點(diǎn)之間的距離和已知的距離相比較，作為展繪導(dǎo)線點(diǎn)的檢核，其最大誤差在圖紙上應(yīng)不超過(guò)±0.3mm，否則導(dǎo)線點(diǎn)應(yīng)重新展繪。

10、測(cè)圖前有哪些準(zhǔn)備工作?答：測(cè)圖前除做好儀器、工具和有關(guān)測(cè)量資料的準(zhǔn)備外，還應(yīng)進(jìn)行控制點(diǎn)的加密工作（圖根控制測(cè)量），以及圖紙準(zhǔn)備、坐標(biāo)格網(wǎng)繪制和控制點(diǎn)的展繪等準(zhǔn)備工作。用比例尺在圖紙上量取相鄰導(dǎo)線點(diǎn)之間的距離和已知的距離相比較，作為展繪導(dǎo)線點(diǎn)的檢核，其最大誤差在圖紙上應(yīng)不超過(guò)±0.3mm，否則導(dǎo)線點(diǎn)應(yīng)重新展繪。第二次作業(yè)13、經(jīng)緯儀整平的目的是使視線水平。(錯(cuò)誤)

1、地面點(diǎn)到任意水準(zhǔn)面的鉛垂距離，稱為該點(diǎn)的相對(duì)高程。（正確）11、直接用于測(cè)圖的地形點(diǎn)或施工放樣的點(diǎn)稱為碎部點(diǎn)。（正確）3、方位角的取值范圍為0°~±180°。

(錯(cuò)誤)15、與水準(zhǔn)面平行的面稱為水平面。（錯(cuò)誤）19、地形圖的比例尺有多種形式，常用的有數(shù)字比例尺和圖示比例尺。（正確）7、系統(tǒng)誤差影響觀測(cè)值的準(zhǔn)確度，偶然誤差影響觀測(cè)值的精密度。(正確)

12、確定直線與標(biāo)準(zhǔn)方向的角度關(guān)系，稱為直線定向。（正確）2、天文坐標(biāo)的基準(zhǔn)面是參考橢球面。(錯(cuò)誤)17、用鋼尺精密測(cè)量距離時(shí)，要對(duì)最后一尺進(jìn)行尺長(zhǎng)、溫度和傾斜三項(xiàng)改正。（錯(cuò)誤）10、地面上某點(diǎn)真子午線方向和磁子午線方向之間的夾角稱為坐標(biāo)方位角。（錯(cuò)誤）5、在水平角的觀測(cè)中，方向觀測(cè)法主要用于觀測(cè)單角。（錯(cuò)誤）16、用經(jīng)緯儀測(cè)量地面兩點(diǎn)間的距離時(shí)，必須測(cè)出水平角。（錯(cuò)誤）8、具有控制全局作用的網(wǎng)點(diǎn)稱為轉(zhuǎn)點(diǎn)。（錯(cuò)誤）14、閉合水準(zhǔn)路線各段高差的代數(shù)和應(yīng)相等。（錯(cuò)誤）20、象限角的取值范圍為0°～90°。

(正確)

18、高程測(cè)量時(shí)，測(cè)區(qū)位于半徑為10km的范圍內(nèi)時(shí)，可以用水平面代替水準(zhǔn)面(錯(cuò)誤)

4、地面上任意兩點(diǎn)之間的絕對(duì)高程差等于其相對(duì)高程差。（正確）9、測(cè)量工作中用水平面代替水準(zhǔn)面后，對(duì)距離的影響很大。（錯(cuò)誤）6、測(cè)量工作必須遵循"從局部到整體，先碎部后控制”的原則。（錯(cuò)誤）

第三次作業(yè)1、用測(cè)回法觀測(cè)水平角的觀測(cè)值如下表，完成表中的各項(xiàng)計(jì)算。（10分）水平角觀測(cè)記錄測(cè)站豎盤位置目標(biāo)水平度盤讀數(shù)°′″半測(cè)回角值°′″一測(cè)回角值°′″備注O盤左A000024584830584827B584854盤右A1800054584824B23849182、用雙盤觀測(cè)豎直角的觀測(cè)值如下表，完成表中的各項(xiàng)計(jì)算。（20分）豎直角觀測(cè)記錄測(cè)站目標(biāo)測(cè)回豎盤位置豎盤讀數(shù)°′″半測(cè)回角值°′″豎盤指標(biāo)差″一測(cè)回角值°′″各測(cè)回平均角值°′″備注OA1盤左813812-82148
