研究了正弦条码利用相位对位移进行编解码的原理及其在远距高程定位中的应用。
The displacement encoding and decoding theory of sinusoidal bar code and its application in height measurement over long distance were studied.
结果表明，若仅是为了测定点的垂直位移的高程速率，增加重力测量数据后对形变分析的精度增益十分有限。
Itturns out that the accuracy increase is quite limited by using gravity observation to analyse vertical deformation, if the aim is only to determine point vertical displacement and its velocity.
同一高程处桩的水平位移大于内侧土体而小于外侧土体；
The horizontal displacement of the pile is larger than that of the inner soil and less than that of the outer soil.
