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.

本文用有限单元法按平面形变情况分析了五座锚定板挡土结构，发现分析结果与现场实测数据相当接近。

Five of these anchor slab structures were analyzed by finite element method in plane strain case, and the results of analysis are fairly close to the data obtained from field observations.
