1.測點(diǎn)分布規則給用基面變換求取最小區域法平面度帶來(lái)方便；
2.測量截面較少，且每個(gè)截面都有一定的代表性，測點(diǎn)為特征點(diǎn)，便于反映被檢鑄鐵平臺平面總的彎曲態(tài)勢及其平整性；
3.通常對角線(xiàn)、長(cháng)邊、短邊的長(cháng)度均不相等，需采用不同跨距橋板檢定，數據處理較麻煩；
4.這種按對角線(xiàn)截面為基面進(jìn)行平面度評定的方法稱(chēng)為對角線(xiàn)法，該法實(shí)際上只是將觀(guān)測結果統一到同一個(gè)基準面上，而沒(méi)有避免由于多余觀(guān)測產(chǎn)生的重復點(diǎn)的重復誤差，這種保留矛盾的計算方法是不夠合理的，因此該法需檢驗與控制其重復誤差的大??；
5.測量精度較高，該法易掌握、使用方便，得到了廣泛應用。
Characteristic of Metric Wiring Point to
Cast Iron Platform
1. The rule of measuring point distribution
brings convenience to the calculation of minimum zone flatness by base plane
transformation.
2. The measured cross-sections are few, and
each cross-section has a certain representativeness. The measured points are
characteristic features, which can easily reflect the overall bending situation
and flatness of the tested cast iron platform plane.
3. Usually, the length of diagonal, long
and short sides are not equal, so different spans of bridge slabs are needed to
verify, which makes data processing more troublesome.
4. This method of flatness evaluation based
on diagonal section is called diagonal method. In fact, this method only
unifies the observation results to the same datum plane, but does not avoid the
repeated errors caused by redundant observations. This method of calculating
the retention contradiction is not reasonable enough, so it needs to be tested.
Controlling the magnitude of repetitive error;
5. The measurement accuracy is high, the
method is easy to master and easy to use, and has been widely used.
