A large scale model test was carried out to study the variation of lateral swelling pressure of expansive soil acting on retaining wall due to deep inundation.

通过大型模型试验，研究了深层浸水条件下膨胀土挡墙侧向膨胀压力的变化规律。

These opposite effects may lead to additional lateral pressure and make active earth pressure of soft soil bigger than the theoretical value.

在土钉-排桩复合结构中，土钉的加固机理使软土主动土压力减小，而土钉的锚拉作用又可能使软土产生附加侧压力。

The relationships from vertical soil pressure, axial stress of anchor, lateral displacement of foundation to construction process are got by test data analysis.

通过对试验数据的分析得出了土中竖向应力、锚杆轴向应力、基坑侧向位移与施工过程间的变化关系。
