粉砂粉土中，基坑被动区土体水平侧压力系数与竖向有效应力关系的研究还鲜有报道。
The relation between lateral pressure coefficient and vertical effective stress in passive region in front of wall is still given less concern.
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。
These opposite effects may lead to additional lateral pressure and make active earth pressure of soft soil bigger than the theoretical value.
该模型土层定义为弹性，以面面接触对模拟桩土接触面，温度荷载模拟土层对桩的侧压力。
The face-face contact pair is used to simulate the pile soil contact face, and the temperature load is used to simulate the side pressure of soil layer to the pile.
