ansys对挡墙进行分析。通常挡土墙都比较长，可按平面应变问题考虑，如此其计算模型相对较小。在考虑其相互作用时，也涉及确定合适的土体尺寸问题。与桩土问题类似，也需要根据计算结果确定合适的土体尺寸，一般根据边界土体应力确定即可。

-ansys on the wall for analysis. Usually longer than the retaining wall, according to plane strain problem considered, so the calculation model is relatively small. When considering the interaction also involves determining the appropriate size of the problem of soil. Similar problems with the pile and soil, but also need to determine the appropriate size based on the results of soil, the soil generally in accordance with the stress boundary can be determined.
